How to handle the cramping?

Redittors, I'm in need of some assistance. My WL journey began exactly one year ago, and I've been on wegovy for that stretch of time. It's helped me lose over 60lb and I've dealt with very little side effects. Since I'm still not at my GW and my weight loss stagnated, my doc prescribed me MJ. I took my first dose yesterday. When I say I'm experiencing one of the worst gastrointestinal cramps of my life right now, it's not even an exaggeration. It's like having diarrhea without anything to sh*t so I'm just on the toilet, in pain and having cold sweats. Has anyone experienced this? Does anyone have tips for dealing with it that don't involve an exorcism? Thank you
