I told you before that I trust on
phentermine rather that any other Diet pill...........As you are already taking your Phentermine Dose you should stick with that only....some times change of Medicine does not suit ones person So consult your doctor before makin any of change....................
But either you take phenterminr or
phendimetrazine both of them will work more faster if you manage your Diet Plan...........Just start workout and start doing some excercise.................
Because
Diet pill + Excercise + balanced Food= Weight-Loss
Best of Luck!!!!!!!
