well, muscle milk is lactose free and the GNC you mix on your own so you dont need to add milk and if you are you could try an almond milk, which is pretty tasty.
what flavor of the muscle milk? i had the light chocolate and its not too hot but the vanilla creme was pretty good. Wierd for me to say that i am a chocolate lover through and through.
My wife was 248 and the Doctor did not have her do any special diet, and I asked about that for myself too when I went in for my consultation and they said i did not need one either i was about 220 at the time. So possibly your weight isnt high enough for him to put you on a special diet.
February 9th here, i am anxiously counting the days so exited for the day to come. I was happy to not have to worry about any pre op diet, unfortunatly i ended up gaining about 20lbs trying to get all the buffets out of my system.
