Hi Lisa - I'm now 4 months post op and have lost nearly 100lbs, like Caroline i can eat mostly anything and drink whatever i want, and so far i've not dumped, all this low calorie stuff is rubbish, you will be able to eat so little and your body will absorb so little the calories wont really be an impact, and if you want to go out and have a good drink up then do, lifes about living and enjoying your new shape, and the best thing is the weight will still drop of. I dont follow any sort of diet at all, though i try to eat real home cooked food rather than ready meals.
Dispite what it may seem there is life after the bypass !
