Waiting to have sugery -here's a lttle advice learned the hard way

I'm 1 week post op and down 20lbs yeah! Let me give you one little advice on what can make this process easier. I blew off the 2 week fast (ate a giant bowl of Mint Choc. Chip ice cream at 9pm the night before surgery), smoked right before heading to surgery and drank soda up until 9pm the night before surgery. Giving up nicotine, caffeine and food in one day contributed to my really sucky 1st week post op. Withdrawal from these things is no joke. I literally lost my mind for about 2 days. I was put on some sort of anti-anxiety meds, slept for 2 days and finally woke up as me again. I lost my mind to the point that I told my mom to take my son because I could not care for him. I layed in bed and cried and cried. I had one nightmare after another, often screaming vulgarities so loudly my mom would run to the other end of the house to shake me awake. I shook inside and out and could not have a cohesive thought. I was terrified. Woke up today though as me again thank God! I know my will power did not allow me to do the right thing but if you have some willpower, give this stuff up before the surgery so you are not healing and withdrawing at the same time.
