While I've been full carni, I virtually stopped drinking coffee having one maybe every 2 or 3 weeks. Then about six weeks ago I got a taste for it again and thought 'it's not doing me any harm'. And I started having it more to teh point of a small cafftiere every day - about 3 espresso cupfulls, which I'd drink at the same time. From beans I ground myself. Very nice.
But - about three weeks ago I started getting lower back pain, which has been a weak point on and off, at one stage leading to me getting rid of my bikes. So it was starting to worry me. It wasn't spasming, but a constant pain for a couple of hours from sitting at my desk in the morning and wore off throughout the day.
I thought maybe it's the coffee, so my last one was last saturday. Started easing on tuesday and today it's been 10% of what it was. If it goes completely I'll know it was the coffee.
