I'm sorry to hear the diagnosis james, but at least there is no more guessing. I also suffer from intestinal issues (recurring colitis) and pot definitely makes it easier to deal with. Suffering through some issues now, most likely will be forced to take oral steroids again until I can get back to eating normally. Don't ever take healthy bowels for granted gentlemen!
I hope the butter and the meds bring you relief James so you can hopefully start feeling healthier again. IBD comes and goes, I'm not sure how Crohn's is treated, but oral steroids usually help me feel better within 2-3 days for my form of IBD.
