Hi im 18 and weigh 140, I tryed 300 mg of Phentermine. I almost got in a fight and I felt slow motion. it was like heat and energy was flowing out of my body kinda godly like n the world was away from me I couldnt calm down but my friend got me away. Also they made me randomly angry then I'd be happy then sketchy n sick n weird not knowing how to feel. Then weird body feelings, tingling in my tongue n arms sometimes then numb n cold chills in the back of my brain or felt like hair growing, bad heart pain, hands would swet, muscled locked up sometimes, hallicuniting,blown out eyes n scary extreme sensitivity to sun light. I've done a lot of research n couldn't find anything to help n didn't see much bout people taking as much as I did.
