Keppra - coming off of meds

I had a one week time frame in July 2006 of which I had multiple seizures Monday and Tuesday, 2 on Thursday, and one on Friday. I was originally on Dilantin and then switched to Keppra of which I have been on Keppra for almost 4 months. Now my Neurologist is thinking that I might be alright if I come off the meds. I want to get pregnant sometime towards the middle or end of this year so we (the Doctors, my husband and I) think it may be better to try coming off the meds sooner then later. My neurologist says everything may have been an allergy to a medicine (I was having migranes, which are now gone) or something else but not technically epilepsy. I had two EEGs, one in the hospital during a seizure, and one in December, of which both came back regular and non epileptic. Anyway, I am in the process of coming off of my Keppra and was just wondering if anyone else has been taken off of this... ? I know you have to come off really slow but I'm a little peranoid and am scared of coming off of it too quickly. Although so far I have not had any problems. I started at 500 twice a day, then 500mg once a day, and am now at 250 once a day. I was just wondering if I should continue to reduce that to 250 every other day or if this is where I should cut it off. I just figured I would ask to see what others have been told. Sorry this is so long and I thank you in advance for your reply!!!
