You aren't silly... Most of my meds have "weight gain" as a side effect. I'm the size of a blue whale, I don't need more weight gain - but I do need to be able to move, to have my sleep controlled more and to have my funky migraine things controlled better. I am working on the weight loss, and I always will be.... Sometimes the weight gain is the lesser of 2 evils - I know it is for me....
