Phentermine
"I was on Phentermine for almost 2 months, I started out weighing 175 pounds and now I am at 155.50. I started out with bad headaches, numbness of feet, cold feet, tingling legs and no appetite.  I am a 38year old female. I was recently seen at the Dr's office. I went in for my monthly checkup, I was feeling sick my head was hurting bad and I was short of breath. I complained of my feet being numb and my legs feeling tingly. I was immediately taken off the medication. My heart was beating irregular, they said this was a reaction to the medicine and I was feeling sick because my heart was beating irregular. I was admitted from the dr's office to the emergency room. I will now be seeing a heart specialist to see if there's any permanent damage"
