Clonazepam
"I've been on Clonazepam (.5 mg) for almost 6 months now.  I already take Wellbutrin for depression but my anxiety levels were still a little high.  I told my doctor and he prescribed the Clonazepam and told me to "take as needed". Well "as needed" for me is usually 2 nights a week, depending.  If I am feeling anxious, I'll pop one. It has helped my anxiety greatly.  It takes the edge off and brings my level of anxiety down to a manageable level.  In addition, it helps me get to sleep quicker and helps me stay asleep.  From what I have read about the drug, it can interfere with REM sleep but I wake up feeling fine.  My only side effects are that I sleep too long and wake up feeling groggy/drugged but that's about it."
