Insomnia
"After a couple of days it helped me stay asleep (I used to wake up after a couple hours of sleep and be up all night).  I didn&#039;t have bad dreams, but I did have extremely vivid, kinda weird dreams, which took some getting used to.  However after a while (3 or 4 months), the effectiveness waned.  I started with 50 mg and never went beyond 100mg."
