Ack! Headgear!
Thank goodness I only had to wear it at night! I totally cheered when the orodontist told me I didn't have to wear it anymore. It's been, hmmm, eleven years since I got my braces off and I still have scar tissue on the inside of my cheeks where the bits the headgear slotted into rubbed. As for the food groups, I ate them all and just got real good at sucking bits out of my braces afterward (a habit that took quite some time to break once the hardware had been removed).
Drink coffee and do stupid things faster with more energy.
