Surgery in December ..meh

Had my first appointment today with my surgeon. My insurance requires a drug test and you have to be weed and tobacco free..I'm not a smoker but unfortunately I took a few puffs of my bfs cigar last weekend so I can't start my 6 months of dieting till its out of my system which takes 30 days soo yeah..I also have to stay away from second hand smoke. Good news is my insurance is really easy to work with and get approved as long as I test negative and do my 6 month diet! But ill prob start my 6 months beginning of July and I need to try and lose 20 pounds since most of my weight is my tummy. So mery Christmas to me? Lol
