I actually had to learn to NOT eat anything during the middle of the night!
For one reason, the EX (yea, it started with her!) forbade me to eat anything at night. But, it was worth it, when I didn't really HAVE to eat anything. I had developed less stomach aches then.
But, after a while, when i was real active with Aikido, I didn't have enough in me and was starving in the middle of the night, so I just took a few tablespoons of Strawberry Jam (The only Jam in the house) to pick up my sugar level, so I could go back to sleep.
Now, I still try to avoid eating anything during the night, or at least make sure I had something to eat a half hour previous to going to bed.
Before then, I used to attack the cereal cabinet when I was living in the States!
