depression
"I've been on 300 mg of Effexor for depression and anxiety for years.  Last year I was diagnosed with fibromyalgia. My rheumatologist  gave me amytriptyline because I couldn't sleep.  Wow!!  What a difference.  I can sleep.  I'm upbeat.  I feel great.  I am one of the few who has hallucinations - only at night, only when I wake up not long after I've fallen asleep.  Usually I see bugs - bees, spiders, etc.  They are always black because it's dark in the room.  Once I saw white feathers coming from the air conditioner.  They usually stop as soon I become coherent.  It was scary at first, but now I'm more conscious of it, so I usually just fall back to sleep. It's worth it to have my fibro and depression undet control."
