"i love this drug, but it is not for the casual or lazy user. i find i must take it at nearly the same time every day or i get side effects. i take it first thing in the morning, and i avoid the sleepies by doing something semi active for a short time. also, never take this before bed... it can cause sleeplessness and nightmares. i take lanzaprozole at the same time for gerd, so avoid any stomach upsets. the nightmares went away after about 4 weeks from starting. i feel so normal now-- energy level has returned and the blues are gone!"
