Invisalign HURT really badly. Any suggestions?

I went on vacation for a month and i forgot my invisalign, I couldn't find the try i was on when i got back so i went to the next one. MY TEETH HURT SO BAD! its tight and i can manage it but when i go to sleep and wake up the next morning it HURTS really really badly! i paid a lot of money and i don't want a refinement because i already had one and this is only the 4th tray. any tips to reduce the pain to help me power through this!
