Drink plenty of water and have the paracetamol to hand..................doesn't sound helpful does it, but if you have been drinking loads of caffeine then you are likely to have a banging headache, but this does go after a couple of days and its an unfortunate side effect of caffeine withdrawal.
I did the same, but took a couple of days off work at the beginning so could feel ill at home :giggle: I had been warned by others who had done it and had a vague idea of what to expect ................think I underestimated the headache tho
