sounds right considering you only have one fill. What size band? how much do you have in?
the first few month you will be able to eat more and more different items. When i started i could still eat bread, rice, Pasta... with no problem. But as you put more and more fill in you will learn what you can tolerate and what you can't. It's all a learning process...
My advice to you is to start now pre measuring your portions. You will still be hungry, but this is when you eat healthy Snacks.... i ate cheese, yogurt, hummus, re-fried Beans, ... sipped on a healthy shake. Start now practicing how you eat. Cut you food in small sizes (no bigger than the size of the nail on your pinky finger) chewing till it is almost puree in your mouth. Take a bit, put the fork/spoon down... think about what your eating with no distractions like TV, a book, talking... You have to pay attention or you will forget and chew, swallow... stuck. It will happen. Remember, no drink on the table... not even Water. Get use to saying NO thanks. When eating out, ask the waitress/waiter to bring a box when the meal is brought to the table. Don't take a bite till you pack all but your portioned sizes. then hand the box over to someone else so your not tempted to go back in. Stay away from the BUFFETT...!!! If you do go, ask to order off the menu. When you can ask for half or kids size meals.
Pre planing is the key. Know what your going to eat in the day. This will help you not make impulsive choices... I am an impulsive eater... i still am. But i have come to terms with my weight loss and my body and i'm in a good place.
Wish you all the luck and keep thinking positive and help your band... help you... and above all.. Listen to your doctor.
