I am fairly new to this still and I am having problems with my sugar dropping! When this happens, I want to eat everything in the house

I can't seem to get this right. I am always under my calories but I have trouble staying in range with the rest (cars, sodium, sugar, etc.) I have quit drinking pop! Any suggestions? I know I really need to eat small meals 6 times a day but I can't seem to figure out how to work 6 meals in. Help! I am ready to give up!
