Accutane and Weight Gain

Hi Accutane friends !

I started 30mg of Accutane back in the middle of September and I'm in the middle of my third month now on 60mg. I feel as though my middle section and face are so puffy and bloated. I can really see a difference in my body and it makes me sad. I actually started to become a bit more active last month, taking reformer and mat pilates classes three times a week at most. I've been trying to watch what I eat as well and I feel like not much has changed diet wise so idk why I'm so puffy. I'm just confused and wondering if anyone else has experienced water weight or weight gain in general on the medication, and if it came off as soon as your course was done? Or what you've done to lose weight while on the medication? Any advice is much appreciated !
