Nights are the worst for me when I am flaring, too. I can sometimes go from lunchtime or so until mid-evening or bedtime without a lot of problems. The minute I lay down, however, it's all over. Before I went to the hospital last week, I was getting up 10-12 times a night...sometimes every 15-20 minutes.
I continue to have a few more problems - maybe 4-5 times - in the morning after I get up, and then the afternoon break again.
My doc never said anything about eating at night, though I was usually not hungry enough to have much in the evenings anyway.
