First my rep told me it was ok to drink coffee while on Thrive which I later found out could cause a heart attack. Then I started to get bad muscle cramps/jams in my right calf and then they slowly spread to my hamstring. I even went to the Dr and she changed my cholesterol med and it didnt halp. A month and a half later I quite Thrive as I had no increased energy and no weight loss. Within two months of quitting, the muscle cramps/jams went away completely. Thats when I went on-line and saw all the complaints and all the side affects. Asked the rep about this and she said the website says to consult a physician before using this product. I asked her if she tells this to customers before they use the product. She said no. I also found out that the company tells its reps if anyone says anything bad about Thrive, they r bad people and should not be associated with as well as if anyone tells u money isnt everything they r wrong and should not b associated with. Bad company! Anyone else who had bad side affects, bad treatment or no results please report to BBB and especially to the FDA!
