Almost 2 weeks post surgery

Monday will be two weeks since I had my gastric sleeve surgery.  I am scheduled to go back to work on December 1, 2017 so I missed about 3 weeks from work.  I thought the surgery would stop the cravings for junk foods.  While I am unable to eat anything that is considered junk food, I still have cravings for a burger and fries.  I didn’t have the cravings the first week because I felt sick to my stomach.  I am learning slowly how much is too much food for my body.  I started back at the gym this morning, I walked 61 minutes for 2.03 miles as my surgeon wanted to know how much walking I was doing and how much water I am drinking?  I think a lot of my problem is that I am thirsty not hungry.  And so the process begins to trying to live a healthy life.
