Interestingly enough, I gave up coffee 7 years ago and only reintroduced it 3 months ago... And while I've had obstructions that have been very acute and severe during that time (aporox one per year), the symptoms I've been having recently have been different... they're almost constantly with me and partially obstructive and hurt. Since posting here a week ago, I've given coffee up again and am possibly starting to turn the corner. At least I hope so. We'll see It takes months to years to figure out if one particular thing you are doing bears a greater responsibility than another thing you may be doing or simply have going on. When I gave coffee up originally it was for the usual reasons... It exasperated any digestive discomfort or indigestion of which I had plenty. After getting my diet in order, and avoiding antibiotics for years, I thought I could handle it. Either my adhedions have worsened or it's coffee or possibly both. I'm back to green tea for the foreseeable future. I drink Japanese sencha. Avoid herbal like the plague. The Japanese steam their leaves to cure them whereas most other tea leaves are roasted. Less bitter more 'umami.' I get it from an outfit in Japan called O-Cha. Takes a while to get a system down with brewing it, you really need a japanese teapot, but great stuff. The caffeine takes more liquid volume and longer in time to build up in your system, but it's much more even than coffee Less highs/lows.
