I believe i have adjusted to it already. I did not experience any headaches or tiredness towards the end of the day. I did not feel hungry once again, I did experience some cravings though, probably because i was thinking and smelling food as I commute home today.
Tomorrow is the 4th day, im excited to be honest, because i did not expect to last this long. I told myself that I will do it for 3 days and if i can still do it, i'll i continue to 5 days. So, I believe I will do that.
