Invisalign pain!

I am on my first tray and wear it between 23-24 hours a day. I'm on day 5 and my teeth are still so sore I cant bite down on anything. I tried to eat oatmeal and it hurt too much to finish. I have tmj and I grind my teeth at night. Will the soreness let up over time/trays or should I just plan on smoothies until this is done?
