Dietary issues

I am 14 years post op, had an RNY in 2002.  I'm having an issue with evening meals.  I usually have breakfast around 9 a.m., lunch between 12 and 2.  If I try to eat anything in the evening, I feel sick and can't get it down.  I'm not all that hungry then so I don't really miss that meal, just wondering if anyone else has had the same experience.

Are you constipated? When I get like that I know I need to get "clean" to make space for more food.
