I do 2:5 (working week without food, eat only on starting friday night) very often (another one due next week), and I don't have headaches. Basically, I just don't stop coffee! I have one coffee in the morning to get a kick, and that's it.

For metallic taste in mouth the best is sparkling mineral water. Oh and I wear socks in bed, because I get cold (I usually never do!)

personally I don't like fasting just 2 days, you get the 'disadvantages' of fasting (hunger the first day) with very little 'advantages' (autophagy). I think that 3 days is a minimum for a good 'return on investment'.
