Time To start whinning my self off caffine

So I am being banded in feb and boy oh boy do i like my iced lattes and soda . Which I have to stop drinking but its all going to be worth it .. I am going to be whinning myself off of them so i dont get caffine headaches which i do get when i dont have any caffine so the doctor reccomned that i do it slowly so I dont get really bad ones when i start my two week diet and than after the surgery plus they have alot of sugar in them so thats not a good thing because of the calories . I am getting reALLY nervous for this surgery but im sure i well do really well with it I am so excited!!!!
