My doc put me on phentermine to help me lose weight that i had gained from taking cymbalta...phentermine is an old drug for weight lose and it is basically an "upper".... when i take a phentermine, my pain disappears and I am full of energy....i have to be careful not to overdo things because I will crash and end up in bed in agony....but, phentermine has got me through the majority of summer vacation so I can stay up to keep an eye on our boys and even be able to do some gardening.... i read here, at prohealth that some people are taking adderall to help with energy so they can continue to work.... I did a little snooping around on the Google (phentermine and fibromayalgia....adderall and fibromyalgia) and discovered that others had taken adderall for adult ADHD and discovered that their "brain fog" cleared up and they had energy and the pain was reduced or eliminated! There were a few people that had the opposite effect but most had good results....it was the same with phentermine....people discovered this by accident! Caffeine does the same thing.... so, why doesn't someone develop a drug to do what these drugs are doing? I think they affect the brain and cause us to make more dopomine or something. anyways, I just wanted to throw this information out to everyone....maybe ya'll know this and I was the last to figure it out....BUT HERE IS THE KICKER-after i take it for a couple months, it doesn't work anymore! so, i plan on talking to my doc about what to do so I can still take it or maybe switch to something else? but, i would like to hear about other people who know about this or have suggestions on how this can keep working.... the difference is amazing!!! i am normally housebound/bedbound and when I take the phentermine, i can stay out of bed all day, with no naps ! i can garden and I can actually go shopping for short trips..... i really wish this would keep working!
