Sibelium symptoms and conditions

I am on Topomac for the last 10 days. I have been suffering from stress migraine for the past 6 months and I took professional help only a month os so back. The doctor started off with Sibelium, but this managed to reduce the occurrence. So instead of 4 headaches I now had 2 headaches per week. After a month of Sibelium, he started me on a 25 mg course of Topomac. I did not realize that this drug would be one which I would end reading so much about. Starting on this drug I immediately started feeling lethargic, sleepy and general tingling in the arms. From the 8th day onwards the dosage was increased to 50 mg per day with a review to be done on the 30th day. However other than the general lethargy, sleepiness, and slight lack of coordination, I feel that the drug has helped me get rid of the pain of migraine. I hope I am not speaking too soon, but I will keep all posted of the progress of my treatment with this drug.
