"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&#039;m at 182.  after that i would take half here and there then stopped  till october. now i weigh 176 i&#039;ve started researching cause of chest pains, tired, headache, all the negatives i&#039;ve read when they were tested, not worth the health risk"
