oversleep effect while on fluoxetine ???

i've always been an oversleeper, my average sleeping hour range is 12 hours straight !!! i know i know, anyway i haven't pulled an all nigher in a while (since before starting to take prozac), and recently i've started taking escitalopram 20 mg then decided side effects were too much so i switched to prozac 20 mg (which i'm familiar with from before) ...

anyway my question is how would my oversleeping affect me now ?? cuz yesterday i had pulled an all nighter for an exam and slept for about 21 hours straight :'( :'( and woke up exhausted; feeling like im gonna faint, can't stand, nauseous, and i have a TERRIBLE headache ... 

anybody know what the hell is going on ??? xD 

When I first started on these tablets I was wide awake all the time.. now I sleep more. I think it is a side effect. I am also wondering if you had slept for 21 hours and had no food that your feeling dizzy etc may also have something to do with that. I feel fuzzy if I synch my bodyclock out of whack by pulling an all nighter as well.. even if I did sleep that long. Also sometimes the more sleep you have had the tireder and less refreshed you feel for some reason. I guess it is like over eating .. you need to find the perfect balance because if you have a mass binge then you feel crappy.

i dont know, i started fluoxetine, 5 days at 5 mg, now one week at 10mg, hard to wake up, morning anxiety, feel terribly nauseous, headache, teeth trembling, dizzy and feel like fainting, soooo fed up with all this meds , i dont know what to do, it would be so nice we can take it in the evening and wake up refreshed with no side effect!

What time are you taking your tablet?

i take it in the morning, would like to test in the evening but i think it is "stimulating" for sleeping
