Thanks for your reply, I am on epilepsy drugs as I was having grand mal and petite mal seizures, loads of them, just after my recovery from the first C.F episode. however there has never been any clear indication as to the reason why! as all brain scans ect. proved negative, so I was started on anti convolsant drugs to help. this was fifteen years ago ish. I have tried to reduce dosage at several points throughout this time but have ended up feeling unwell. about four years ago my dosage was increased due to slight petite mal seizures reoccurring and now they are at max. allowed.
I think B12 may have stopped being given at same time of epilepsy treatment started.
trying to get back on it now because I feel like I have new episode of C.F
thanks for your info. will go back to doctor for more advice.
