OK, folks I have been taking Topamax for just over a year now (150mg day) and considered discontinuing using it due to the tingling. In fact I was reaserching the correct way to go off the drug when I found a reference to the use of the suplement Potassium. I have been taking 700mg per day and and most of the tingling has been been mitigated. I do notice increased tingling when I use vibratory power equipment like snow blowers and lawn mowers. I just increase my potassium dose to compensate.
Best of a headache free life to all !!!
