I started taking Linzess about 3 months ago, for IBS-C. I was 160lbs when I stared taking the medication, 3 months later I am 194lbs. I drink around a gallon of water a day and I work out at least 6 hours a week. I also eat healthy for the most part, I look like I'm four months pregnant and I'm always bloated. I'm 22 and a full time college student. I've considered stopping the medication but I'm scared of the side effects. Any advice???
