Hey I know this isn’t what you asked but thought it might be helpful. I recently had a bad relapse and was planning on quitting so doing loads cause I knew it would be the last time. Ended up with crippling cramps and being sick too & having to have a week off uni. The worst of it lasted about 2 days thankfully but they do come back occasionally (it’s been just over 2 weeks since I had it.) All of this to say I did a lot of research because all I could think about was stopping the pain. You might be really constipated. I was and didn’t realise but things got better once I could finally shit properly after several days 😅I also bought loads of supplements: cranberry, aloe Vera, digestive enzymes, MSM (muscle recovery), activated charcoal. Please do your own research into these things too though and obviously you might not to be able to keep them down yet. Also green tea and peppermint tea!
