Stalls and soreness

Hey there, I am 8 months out and I am 6 pounds literally from my 100 pound loss... I am stalled.. it won't go up won't go down...  anyone incurred this one...  and plus some foods I eat I feel like there is a big rock in my pouch and want to vomit...  some are foods that I always eat and some are retries....  just some insight from others who deal with this would be great

thanks
