Hypersomnia
"I give Vivarin a seven for an OTC medication. I don&#039;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&#039;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&#039;t have the time and I have to pop another Vivarin to keep me going."
