I have been drinking Pepsi my whole life( 23yrs old) I have been trying to kick the habbit for some time now.. I have been doing really well went from 2 12pck a weekend. To 2 12pck a week to on 12 pk a week 2 cans a day. And finally a 2littler a week. Anyways I'm ttc so kicking this habit is a must! I have been drinking a gallon of water everyday. But I still have crippling head aches and get supper dizzy if I do anything from not drinking Pepsi. Any tips or help to kick it?
