I'm new- Wellbutrin

Hi everyone! I'm new here- I'm trying to look for some direction. On Wednesday I had my first seizure ever. I was on 450 mg. of Wellbutrin which they're sure triggered the seizure. The day after the seizure, they did an EEG and there were still spikes. My question is- if there's Wellbutrin still in my body, would that cause the spikes, or did the Wellbutrin uncover a medical condition we didn't know I had?

I'm now on Keppra and wondering how I'm going to get through the next 6 months without driving. :P
