Post-Op healing

I am 30 yrs, I am about 5"7 and am over weight (170lbs) from lack of diet and exercise :(. I have two children, my daughter is 5yrs born at 8lbs 5oz and my son is 2yrs born at 11lbs 9 oz. After being pregnant with a humungous child and giving birth, it has destroyed my belly. My tummy muscles are split by 2" at the widest point. There is nothing I can do about it exercise or diet wise, so I elected to have a tummy tuck. I think I have waited long enough to where my son isn't so dependent on me, plus I have a support system lined up for after the procedure to help me with my children.

I think the biggest problem I am having right now is, I keep wanting to read everything about TT's and while I am doing so I keep getting sick to my stomach and light headed like I want to faint, anyone else feel like this? I nearly fainted at my consult with the doctor and was told it was pretty normal for people to feel that way after hearing all the gory details.

My surgery isn't scheduled until Oct 22nd, so I have some time before the surgery to try to drop some of this weight I have recently put on and to gather up the needed supplies.

Does anyone have a detailed list of the supplies that are recommended for after surgery? I know the common things, medicine, ice packs.... I already have bad lower back pain so I expect it to be even worse after the surgery, besides ice for the back any other recommendations to relieve the pain?
