Intractable migraine symptoms and conditions

I was on Topamax for migraine a few years ago and had to go off of it because my insurance changed. I was crushed!! I was on a lowww dose- only 25mg. morning and night. It helped soooo much- and really- the only side effect was some weight loss and the tingly fingers and maybe weird taste in foods.Also- and maybe it's because I;m relieved of constant headaches- I have MORE energy and even better breathing, seemingly!! ( just now had a problem spelling 'taste'- and have read where that is a side effect but think for me it's just being 51 and a tad flaky with menopause. :) ) I'm back on it now- 25 mg. morning and night- and am very happy. The several times a week migraines ( the real thing) are gone- as are the constant floaters I get in front of my vision, and the things like vertigo and photo-phobia that I have constantly even when I'm not in a full-blown migraine. I just don't get the fatigue, headaches, etc. other people do- in fact, almost nothing by way of side effects. That is no doubt due to the low dose and also because everyone's system is different. I am lucky to have found the one med which nails my migraines! I've read all the posts and am definitely upping my water intake, however- thanks for that head's-up! It never hurts! I would say that anyone with intractable migraine should at least try it- although at a low dose. My doc is very cautious and started at the lowest possible end luckily for me.If you're one of the fortunate people who toleates this med it definitely works beautifully to prevent the majority of migraines in chronic sufferers! It IS expensive, though-even in it's generic form- and I really hope to keep affording it!!
