Managing my hunger

Wow.. Being a bari patient and pregnant is a challenge. I am always so hungry! And the things I want are things that make me sick. Candy, sweets, bread, carbs.. I am trying so hard to control what goes in my mouth. Lots of water and lots of sugar free stuff. Also lots of apples, oranges and peanut butter. I love peanut butter! Lord please help me. I dont want to develope habit that I have changed. The other thing is that I am so tired I feel so lazy! I don't want to excersise or do anything I just want to sit on the couch. Mike of course won't let me , we are hiking and stuff but I do get tired..
