I am on my 2nd week on Tenuate. It is not really working for me. I take it around 11:00am. Yesterday I took it around 1:00pm to see if it would last but it did not. I end up finding something to eat and munch till midnight even till 2:00am. Anyone have the same problem? I was taking Phentermine 37.5 and it worked much better but then it stopped working. So doctor changed it to Tenuate 75mg. I have only lost 1 pound in 2 weeks.
