Oh wow....how I can identify with this post!!
I used to drink Mountain Dew like I would just wither up and die if I didn't have at least 3 or 4 a day. It was my pot of coffee in the morning! When I started LAWL, they said it had to go! I could drink 2 diet sodas a day - that's it. I tried Diet Mountain Dew and YICK!! BLAAAAHHH!

NO THANK YOU!
So I just gave it up all together. I can't say I was particualrly addicted to the caffinee - I just loved the taste! After about 2 months of being on LAWL - drinking nothing but water - I decided "I really would like to have a Mountain Dew. I am going to have one!" So I went to the vending machine at work, got one, popped it open, took a sip.......

It tasted like cough syrup! It was so thick and sweet - I about choked! I promptly poured it down the sink! So - it may not work this way for everyone - but give it some time and you'll probably wonder what you ever saw in that carbonated cough syrup!
