I dont know if this drug is related, but I too have suffered pains in the feet, twitchy restless legs. I have noticed it when I Take Citalopram , not so bad when I half the dose, but gets worse as the dose goes up.
I thought I just had tired aching legs , but now you have mentioned this side effect I do think it is linked to the drugs.

I began taking Phentermine 37.5mg on 12/04/09 - after 7-8 days I noticed that my ankles and feet hurt - nothing bad just a slight pain once in a while.
I have not been back to the doctor for a recheck yet. But did contact them about pains. But med is curbing my weight. Energy levels up! I can deal with slight side effects.

I took phentermine for 3 month.. the weight fell off but I had severe twitches of the feet and 6 mos later still have them. My feet hurt so bad. I would never risk it again. Plus soon after coming off the appetite suppressant, I gained the weight back. Now I have the weight and twitchy achy burning feet. :-(

I just started taking phentermine and within three days I have experienced a great deal of muscle aches in my lower back but mostly in my legs, restless leg at night... I went off of the med for 3 days pain pretty much went away... started taking it again and the after 24 the pain is back, I am pretty sure the med has caused the restless legs. Trying to decide whether or not to cont. on the medication... I haven't been back to my DR. yet to discuss with him... open for suggestions.

I am now experiencing severe leg pain. I have been on phenteramine for about 2 months...
I have bad mood swings... a short temper...
My leg pain is worsening and im having trouble walking. This is a very debating problem for me because im 80 lbs overweight and have been losing 5 lbs a week.
The controversy is... do i just continue the medicine and bear the excruciating pain.
