my name is maria,my question is this,in early 2004 I started going to Dr Gupta,diet doctor to loose weight,I took phen phen for some months lost the weight and even though that I am off of the fen fen for quite sometime,i still off and on get cramping in the chest,restlessness,and then my heart in the middle of the night raises and then slows down so much that I can feel it to the point where I feel that I am gonna pass out,I am not sure sometimes though as I am under a x amount of stress and I know how stress can effect you as well.what should I do as I firmly feel that this is the result of the fen f en pill
