Hi Amy and welcome to the group. We're so sorry to hear about your seizure but happy you found us. (Many members don't get here daily but do check in once a week or so, so you should be hearing from a few more people soon.)
I don't personally have seizures but I'm here for my daughter who has had a seizure disorder since birth. There are very few things her Dr. has ever suggested she not do because of her seizure disorder so if I were you, I'd be looking for another Dr. who is more up to date with her information and thoughts. In fact, all her Neurologists have recommend she go on with life and do things just like any other child. The only thing they asked she not do is competition gymnastics (they were worried about the balance beam/bars in the event she had a seizure while on them and fall) and for us to take extra precaution while she is swimming. So she rides a bike, skates, swims, does karate, plays piano and a multitude of other things.
She takes 200mg Lamictal and 900 mg of Trileptal daily and so far she's not really experienced side affects like she had with other meds so happy to hear that the Lamictal is working for you too. It seems to help many people.
I do hope you'll find a couple friends here to help you get through this difficult time in your life. :)
