I have not gone through RAI, yet. I should be schedule soon for it.
My sister (normal thyroid) who has used Fen-Phen liked it a lot. The
only side effect she had was the first week she took it, she had
trouble sleeping. Her body got use to the pill and her sleeping
habits went back to normal. The doctor she went to told her to take
only half of the dosage and slowing bring it up. That way the side
effects won’t be as bad. Before she starting taking Fen-Phen she
weighted about 180 pounds and now she weights around 135. It took
her about 8 months to lose the weight.
I think your right not everyone is made to take Fen-Phen. It effects
each person differently. My advise is to try it and see if it works
for you.
Good luck. I’m probably right behind in the gaining more weight.
