for starters, i suffer from migraines and take 75mg of topiramate daily. the migraines are rare, headaches arent. my mri and eeg came out negative, only showing i hyperventilate in my sleep. i can second this as i occasionally awake with no air. it lasts for a few seconds but feels like an eternity! i try to breathe but cant, no oxygen no anything! i have lost weight as the result of exercise, not topamax. my memory has become rather poor compared to what it used to be. i had a photographic memory, not anymore! also, when i stand, i have trouble keeping my balance which is accompanied by a blackness that spreads from my outer eyes towards the centre. some days i drink plenty of water, other days little to none. i am constantly sleepy and yet i have trouble falling asleep at night. it is on my way to my room when i get paranoid, though this is not often. i am usually nauseated. by the way, did i mention im only a teenager?! i would greatly appreciate it if someone could help me put the pieces together!
