Surprisingly, the hardest part of the day isn't late afternoon when it's hot and the fast is coming to an end. In my opinion, the worst part of the day is waking up, knowing that you have X number of hours before you can eat or drink. As those hours pass, it gets easier, as I find things to fill that time, and once there's only an hour or two left, I go running, and then sunset comes. The other worst part of the day is right before the sunrise call to prayer, when I'm not hungry or thirsty but feel the need to eat and drink, knowing it'll be fifteen hours before I can eat again. (And knowing that the more water I drink at 4am, the more times I'll have to get up to pee in the middle of the night).
It does feel wrong to be unhappy going to bed every day and then wake up unhappy every morning.
