Another seizure

It has been two weeks since our last seizure and I was starting to get a little hopeful that we had found the right dosing and medicines to control them again. I was wrong! This morning Jayen woke up and had another pretty big seizure. It would not stop. When we thought it was over we laid him in bed so his brain could sleep and recover, but I had noticed his hand grabbing at the sheets. His seizure lasted close to seven minutes. I don't know where to go from here. I'll call Minnesota on Monday. Is this ever going to end?
