I Am Due For A Surgery For Gall Bladder Removal

I am due for a surgery for Gall bladder removal . I am under neuro treatment for a couple of seizure occurrences which occurred after my quitting of job and shifting of residence to a new city with my husband's retirement. I was prescribed Eptoin for 15 days with Levipil twice a day, which continued for three months to start with. Then the Doc stopped all medication. A month later I had a repeat seizure. I was again prescribed Levipil twice a day, to be later changed to Levipil 1gm once a day, (XR). After consuming it for six months, I have now been asked to consume Topamac twice a day (25mg) till next consultation.
I am diagnosed with gall bladder stones now, with sludge, requiring surgery.
How safe am I?
