Hey there. I just started Topamax last night. I took it at 10:15ish when I went to bed. I barely woke up this morning (thank God I didn't have to go to work). I went to the couch and passed out, and got back in the bed and slept for another few hours, and I have been terribly tired ALL day long today. It's 50mg. Is there a preferred time I should take this? The side effects are tiredness and drowsiness and CLEARLY I have that. I normally have to wake up at 5AM for work. I've also had a slight headache all day, but not my normal migraine. I don't like feeling like this. Then again, it's better than feeling like my temples are about to EXPLODE. Please offer me any suggestions.
