I am currently on Avonex injections but will be switching to Gilenya after I lose some weight because I'm on bp med that can't be mixed. I'm also on Tizanidine for my hand spasms and an anxiety med. She talked with their pharmacist and said the meds I need could potentially burn through the newly attached intestines if I had gastric, so she refused for my safety. I'm ok with the sleeve, it's still the tool I need to help lose weight.
