After 2 mos of Phentermine I came off it with Doc's approval, as I was also taking hydrocodone for knee pain and did not wish to "mix",,, My appetite is now totally shot, I have to force food down, and end up burping incessantly ( I have Barrats Esophogus) and also am on Nexium,,, Depression has hit me, bad sleep, etc could this a withdrawal? Whikst I was "on" the drug; it did CURB my appetite, but not eliminate it! any help appreciated.
