well, i guess i am not alone. this is the second time i have been on it. i weighed the pros and cons and figured that the migraines were worse than the depression, mood swings, and the inability to compute simple math. well, i feel differently now, and i think i am going back off of it again. my sex drive is also gone, but i have had a problem with that and the depression for years, just not this bad. i feel i have yelled at my children way too much lately, cuz it is making me so crabby, and i don't think that it is worth it. after reading some of your posts, it has helped me make the decision to go off of topomax for good. i could deal with tingling, bad taste, and weight loss (the only good side effect), but not the other horrible effects.
