Topamax and grocery store

Topamax has completely altered my life. I had a year and a half of daily migraines, with only a day or two of let-up each month -- my migraines are "common", not "classical", just to clarify, and my symptoms are more like that of a stroke victim's.
Now I only have bad premenstrual migraines (no solution to that yet). I still have migraines with Topamax, but it is like they have been pushed way down.....
I'm on 200 mg/day.
Side effects of Topamax: Mostly marvellous! The sexual side effects I really want to say something about, because I couldn't find anything about this when I first had them. Please allow me, and forgive me for graphically saying this -- this is about anatomy, and I needed to know I wasn't alone when I first experienced this: I experience marvellous spasms in my anus and vaginal walls sometimes, especially during sex, and I've had spontaneous near-orgasms a few times (though once in a grocery store, which was NOT NOT NOT pleasant). My libido has skyrocketed. It's been wonderful. It's been beautiful.
Sometimes I get a definite "Topamax buzz", especially in the afternoon. I sleep much better, and with a migraine can actually push myself, whereas before it was the end of the world. I can push myself, period. That used to be an impossibility.
Definitely, Topamax impairs my ability to speak sometimes. But my ability to think? It's improved 100%. I used to be a writer, and have now returned to this. It would have been unthinkable before Topamax.
I have intense tingling in my extremities, which can be awful at times. I find the negative side effects most unpleasant some days, like the facial twitches -- mostly the left side of my mouth, and sometimes both of my eyelids (like right at this moment). The fatigue, blech.
But honestly, compared to the migraines symptoms, these side effects are a dream. .....And the weight loss is a bit worrisome at times -- though my body looks great I always have to worry that I'm eating enough. I am getting my life back now. Topamax has some wretched side effects, but some beautiful ones too -- it re-opened my mind, gave me focus again.... and the migraines were hell. I am so very very grateful for Topamax.
