I was recently on a course of medications whose side effects include possible weight gain. I've been exercising and eating sensibly but was horrified to find that some of the clothes that fit me just two weeks ago are now tight. I suspect this is a temporary thing, but it is pretty upsetting nonetheless. It will, however, mean that I can't buy clothing until my weight goes back down (it's always easier to pile it on than take it off) and it will also force me to be more imaginative in coping with the summer heat and humidity. Ironically I had just started to lose weight so this is doubly frustrating. Of course, I've packed it on where I am biggest--my back and thighs. At least I know the culprit but it still leaves me with more weight to lose and takes me back to where I started from.
