I just started taking Paxil 10mg on tuesday night. Immediately after i took it i felt a bit of head pressure and a very very slight headache. I literally could not sleep the entire night. I trucked through Wednesday as best i could, which actually wasnt that bad, but by 6 pm i was fucking exhausted and passed out, woke up 2 hours later, took my 2nd dose of Paxil 10mg and passed out again and slept pretty well. Thursday night i took the same dose again and i couldnt fall asleep again..... I'm not sure if this is the AD or just my anxiety about taking the AD. I'm definitely overanalyzing it and i constantly worry about something going horribly wrong while im on it. So im always worried about whether im going to fall asleep or not. Its so frustrating. I have to study for classes but i just feel so tired. Whats going on?
