User Reviews for Caffeine

NoDoz (caffeine) for Hypersomnia: Gave me the speed jitters, irritable, and still tired and sleepy only now I'm grumpy too.

NoDoz (caffeine) for Hypersomnia: I love No-Doz (caffeine citrate). Way cheaper than red bull, easier on the stomach than coffee, no stained teeth or coffee breath.

Vivarin (caffeine) for Hypersomnia: I give Vivarin a seven for an OTC medication. I don't sleep well at all at night and I usually average 3-4 hours. I stay in pain so when my alarm goes off in the morning, it is much easier to put a tablet in my mouth along with my pain medication and reset the alarm for one hour later. When it goes off I feel much better for it has helped awaken me and the methadone had started to work for the pain. It doesn't upset my stomach as much as the No Doz. Then later if I want a cup of coffee and I have time to drink it I can but usually I don't have the time and I have to pop another Vivarin to keep me going.

Vivarin (caffeine): Never got used to drinking coffee, my stomach could not really stand it and energy drinks did only go so long before their side effects started to kick in and affect my health. After the age of 25 I found myself being so mentally tired all the time and would take several hours to fully awake no matter how many hours I slept. I tried a travel size pack of Vivarin once at work and felt the difference right away, after only 10 minutes I was able to concentrate and finish what used to be my 2 hour paperwork in about 30 minutes. Have not had any side effects when I take it as it is described and there was no boost limit since it only woke me up! I would not recommend taking more than two pills at once or with any other caffeine product though!
