Another day of exercise

I have really been struggling with this food allotment. Since I get up around 3:45 am I start eating early so I am running out of food before I run out of day. I actually had to eat more food today than I am supposed to coz I actually feel like I am starving myself. This is so frustating and I am having a hard time being so weak at work. I do ok on the weekends when I wake up later. I'm not sure what to do coz it defeats the purpose of watching what I eat when I have to eat every 2 hours. I have to eat before I work out or I have no strenght also. GRRRR!!!
