"I have been on cbz for 35 yrs.  20 yr 600mg / 10yr 400 mg / 5yrs 200mg

Since then no grand-mal . However absences remain on 600mg level.

So I (slowly) deminished the dose two times and the absences became 

fewer ( first 10/yr.  now  2-3/yr) .  Cbz worked well in preventing GM 

seizures but absolutely not in case of absence seizures.

Five years ago I had one seizure because I thought I could stop taking 

cbz.  After two days it went wrong and I returned to 2x 100mg.

So don't do this. It is bound to end in a G-M!!!!"
