Weight loss after pregnancy

Hey ladies, I know that it has been a while since I have posted anything! I finally had my little guy Colton on January 13th!!!! He has definetly stolen my heart and change my life completely. I gained about 60 lbs with my pregnancy due to having Polyhydramnous  and lost  40 lbs immediately. I just can't seem to lose this last 20 lbs. Any suggestions???? I went back to my bypass surgeon and they prescribed me Phenteremine to help curb my appetite and it helps with that but I have not lost a single pound. I'm so fustrated, I just want to fit back into my skinny clothes again!!!

I struggled to lose the last 10lbs of the 35lbs I gained in my pregnancy. Even with only 10lbs to lose, I couldn't get into anything smaller than a size 8/10, and pre-baby I was a size2. When I started back to basics, I found out I was pregnant again, so I couldn't continue low carb. I simply have to go back to strict post-op basics, 4 meals a day, no snacks, low carb always does it for me.
