Drugs or Coffee?

ahhh sweet sweet black nectar if the gods, why doest thou forsake me?

My 'No Grains in June' Challenge has been going quite well, so well in fact that I have slipped in two areas because I was feeling so good! Mainly I had forgotten several doses of Doxcycline (It's easy to remember when you are feeling bad - it's a constant reminder!) and I have gotten back into my morning caffeine habit (Mark convinced me it was OK - and it wouldn't have taken even that much) . I am still 'Mostly' Grain free (I will expand on my small lapses in a future post) and have been exercising a bit more and feeling quite good. However after about 5-6 days of morning coffee and  no drugs I am getting dizziness and more finger numbness and now carpal tunnel. Is this Lyme again? Is it my body reacting to caffeine? I am not sure and can't really decide which is worse :(

One thing I know: I'm going back to start over in these two areas. No more coffee and back on the drugs (now a full year into them) at least until I can get back to normal. Then I will have to experiment to find out what is happening.
