Re: Pain: It is quite possible you are A) Eating too fast, B.)Taking too large of a bite, or C) Not chewing your food enough. In the beginning these three things are a must, or you will feel a lot of pain while eating. Try working on these and see if it helps. Keep your bites to about the size of a pea. Put your spoon or fork down between bites, and be sure to chew that food until it's like a liquid.
Re: No weight loss: You just had surgery, and this is a long journey. Try being more patient. It will happen. One day at a time.
Re: Cooking with Seasoning: I sure do it!! I'm not going to be stuck eating cardboard. If I were, I'd just eat... cardboard.
Re: Eating Pizza: IMPO I would wait for as long as you can stand it before trying anything like that. They sleeve our stomach, not our brain. Chances are you can slip very easily back into bad habits - and especially since you haven't started working out yet, that is a very high calorie food and full of fat... preservatives.... just not very nutritionally sound. Your stomach is prime real estate now, fill it with foods your body needs to survive.
Wishing you well in your journey!! No one said this was going to be easy! Least of all me.
