For neurologist only. I have a scheduled open brain biopsy in 8 days. They are supposed to remove a small piece to test, but possibly may take all of it out. I was told to stop taking alot of medications 7-10 days prior. My neurologist doesn't know I smoke marijuana. Should I tell him? Will this matter? And should I stop smoking now? Or will it affect surgery in any way? Of course, I won't smoke the day of surgery..but I need to know when to stop. It helps with my anxiety. And helps me to eat. So I hate to stop for no reason, but I don't want it to affect my surgery..
