I don’t know about long term post op but my antibiotics are for 1 week an I’m presuming u just can’t drink alcohol for the week you are on them. I drank (a lot) the Sunday before my op on a weds (yest) an was just told not to eat or drink anything, only sips of water, 12 hours before op. I got told no spray tan/sunbed 2 weeks before op, although I did wear instant on the Sunday before but made sure it was all properly washed off. No products like moisturiser/perfume/deodorant on op day. Not sure about sex afterwards, think it just varies from person to person and how well u recover. Last thing on my mind right now lol xx
