 3  Sleep aid (doxylamine version) Morning drowsiness. Fewer side effects than with Benadryl (can't remember Benadryl's generic name, it is used also in a different Unisom formulation): no hunger or dry mouth which I get with Benadryl. This is a very powerful drug and should be available in a lower dosage. I am now taking a version (Donormyl) I buy in France which is 15 mg, divisible in two for a 7.5 mg dose, and I am very happy with that dose. Unisom is available only in 25 mg. tablets so that even if one splits the pill, as I did, the dosage is still too large. I recommended this (as the only version available in the US) to two friends who both tried and rejected it as too powerful. F 65 30 days

 2  Insomnia Note: I took Doxylamine Succinate Equate Brand. Grogginess and lethargy on awakening; after a few weeks using half tablet (12.5 mg) at bedtime, couldn't fall asleep. Or, if asleep, felt awake. Worked well initially but taking a few nights in a row caused real problems. This stuff, even at 1/2 strength (12.5 mg) caused insomnia, and also caused horrible irregular/doubled and racing heartbeat. Very stupid/scattered thoughts the next day, scrambled and disorganized. Nagging feeling of very empty stomach during day. It took me about 2 weeks to figure out it was exacerbating my sleeplessness. Couldn't fall asleep; couldn't stay asleep for more than 3 hours. Dangerous drug for some people. I would recommend being cautious with this medicine. F 63 3 weeks

 4  Occasional sleep aid I experience mild personality suppression the next day, but few other side effects. I use the Unisom sleep tabs, but have learned to break them in half, and only take 1/2 tab as my dose. When I use them I take it by 9 PM and am in bed by 9:30, as I get up at 6:30 AM -- so I'm able to get a full night's rest. Taking only the 1/2 tab seems to make it much easier to control the next day side effects, yet I always get a deep sleep. I find I take 1/2 tab maybe once a month when I need to catch up on my sleep.

 5  To fall asleep sooner A full pill made me dopey until 5 p.m. the next day. 1/8-1/4 of a pill has worked great for 16 years. I fall asleep in 1/2 hour, only wake up once to use the restroom, fall immediately asleep again, and wake up refreshed and alert at 6 a.m. One cup of coffee does the final morning perk up. Take 250-500 mg of magnesium before bed to soften stools. 59

 3  insomnia I got a great nights rest. Took a whole pill first night. Then last 6, i only took half. Regardless of amount, i woke up to total lethargy. Left me with a dry throat too. I was useless at work until afternoon. I gave it a week to see if my body would get used to it. I will not take it anymore. M 57 7 days

 5  Insomnia I am using Doxylamine already for a few years. I live in Australia and take it in tablet form with the brand name Restavit. However, I take only 1/2 a tablet (12.5mg) about an hour before going to bed. I then take also a Valerian capsule and 1/2 teaspoon Tryptophan. The combination seems to work exept when I have been overstimulated by having visitors or working too late on my computer etc. I have Fybromyalgia and find that the anti-histamnine is something I also need for some of my allergies. So far I have not found problems with taking this but I may not recognise them because of the complaints I have with Fybromyalgia. F 56 7 years

 1  Insomnia I didn't realize until reading all of these reviews that this medication is responsible for my heart palpitations, anxiety and tight chest! I dreaded bedtime and had sleep anxiety but after 2 weeks without taking it everything went away!!! It was also making me gain weight which I could not figure out! Hate this crappy med! Don't take it!!! This medication also was also responsible for my tight chest and squeezing sensation which hurt and felt like i was having a heart attack all the time! F 55 6 months

 3  Insomnia Sometimes it worked well for me, helping me fall and stay asleep for most of the night. Other times, however, I felt exhausted, spaced out and foggy the next day, and also suffered nausea on a few occasions. I also experienced bizarre, vivid dreams on a few occasions after taking this medication. Doxylamine succinate is supposed to be the most sedating over-the-counter medication available, so use caution when taking it. When taking this medication, make sure you avoid other sedating substances such as alcohol, benzodiazepines (e.g., Xanax, Klonopin), and prescription sleeping pills (Ambien, Restoril, etc.). Because of the potency of this medication, you may want to start out with a smaller dose—half a pill, say, which equals 12.5 MGs—to see how you react to it. M 54

 4  Insomnia Having used sleeping meds for years and after having become highly addicted to them, Unisom brought me wonderful relief from extended insomnia when I had to stop the sleeping pills. Be warned though! I now have HYPER acidosis! Have to take up to 80mg's of acid blocking P.P.I's due to a totally messed up gastric system now. This has lead to ulcers and now gout type arthritis which the Physician says all stems from having used Unisom for close on 3 years. F 51 3 years

 4  Insomnia Lingering grogginess in the morning. Even though this is an over-the-counter drug, as far as inducing the feeling of sleepiness, it is one of the most powerful I've tried and, in that respect, works better than both Ambien and Lunesta. The problem with it for me is that it can take over an hour to kick in -- but when it does you'd better be in bed or close by. It's so strong that I have to buy it in the oval tablet form and break them in half. If I took a whole one, I'd still be in a fog for over half of the next day. As it is, even with the half tablet, I'm still too groggy in the morning which is why I don't use it more. But it's a very effective sleep medicine. M 51 18 months
