With the exception of couple of cups of tea in Yorkshire at the weekend, have almost completely given up caffeine (currently green tea & decaf coffee only and moving to green tea decaf in about 10 days when finished off existing supplies). Up until 2 weeks ago had 1-2 pints of coffee / caffeine daily.
Had initial 3 days of migraine type headaches & accompanying grumpiness but seem to have passed through that now. Feel better for it. Sugar next – by end of April if not before.
