A progress report - I tried drinking more water (but I dont think this was a problem as I always drink about 2 litres of water a day) and the headaches remained - so I took a break for a few days and then only did half a CD a day (It took me 4 days for the first 5 CDs and 10 days for then next 3 - so I slowed down the pace a lot ) and everything is OK now. Probably just a way to tell me to take it a bit easy....
