I had VSG surgery 6/14/2016. I didn't lose much weight at all. I noticed a problem when I started eating solids. I was told to only eat 1/4 cup at a time. I did that and always felt hungry. Stomach growling hungry. I kept getting headaches my attitude changed I was miserable. I told the NP and she wrote me a script for phentermine and sent me on my way. I took it and lost another 20. I stopped taking it and gained the 20 pounds back. I don't know what to do now.
