"i am 38 year old female who has suffered from severe insomnia for 6 years which has gotten much worse. i have been taking 10 mg of ambien which worked well initially (about a year) until is stopped working. i wake up at 2:30 am and cannot go back to sleep. i have also tried all typically prescribed sleeping medicines to no avail. i was diagnosed with depression. i am taking 20mg of prozac and recently 25 mg of seroquel. i was worried about those who gained so much weight on seroquel as i am a fitness fanatic. 1st night i took it at 7:30pm, woke up feeling very groggy and out of it all day but did sleep better the first night. 2nd night, i took it earlier 6:30pm and noticed my legs twitching. slept and felt better taking it earlier. haven&#039;t noticed any cravings."
