I have been on Phentermine for 1 week. I have experience some
heavyness in my chest. Has anyone else experienced this?

yes, I also had s small feeling of being out of control. I quit when I was always feeling like something was sitting on me and then driving down the road feeling like I wasn't controling the car, it was controling me. I have talked to others who had the same type hallucinations. I hope you don't have them. Good luck

Hi lorim. Have you had any more problems with your weight loss plan? Have you lost anything with it? Good luck and much success on your journey.
