I have takin phetermine to lose weight, however, I had an allergic reaction to it so I have been on glucophage and that isn't helping.....I go to the doc on monday and I am thinking about taking the byetta shots but am wanting to know if someone has done this and what can I expect? I have Metabolic syndrome and premenapousal so that makes it hard to lose weight along with the slowing down of the metabolism anyway....Thanks for your advice!
