"i have been on phentermine 37.5 and topamax 25mg since february 3rd 2016. i noticed immediately that i cannot drink carbonated beverages anymore after yelling at the poor fast food server that there seltzer machine was bad. i now only drink water or occasionally juice and tea. i did not change my eating habits during this first month but i did notice i would get full faster. i then began noticing that i was eating less and often times having to remind myself to eat. i am 5&#039;8&quot; and began my weight at 311lbs as of march 3rd 2016 i am 290 lbs. this month i have added daily walks around the block. as time goes by i will increase my distance and begin eating a little healthier."
