Has anyone else been gaining weight like crazy on Orkambi? I know weight gain is one of the positives of Orkambi, and I was looking forward to hopefully gaining a few pounds. I have been on Orkambi for about 2 months now, and I have gained about 13 lbs. I don't want to gain any more weight! Right now it is a little funny that I am having this problem, but I may need to get myself on a diet soon!
