Phentermine
"I started taking them in May 2015, I weighed 196, first week I lost five lbs, I did get dry mouth dizziness, constipation, and insomnia, had to force my self to sleep, and doing Zumba with this pill and a Herbalife pill with or without it together I felt like my heart was jumping out of my chest when exercising it did give me a boost of energy but I started freaking out about it, also my bones like the joints started hurting.. Think they warn u to take calcium or iron pills, vitamins. Month later I'm at 182.  After that I would take half here and there then stopped  till October. Now I weigh 176 I've started researching cause of chest pains, tired, headache, all the negatives I've read when they were tested, not worth the health risk"
