Feeling full all the time

I'm watching my portion sizes, getting my protein in, trying to get in some fiber (don't ask)  and all the water I need to get in a day - I'm feeling so full lately. Like I swallowed a whole watermelon. This has been going on for a few weeks. I'm feeling uncomfortably stuffed, close to being painful. I have no appetite really, I have been eating by the clock just to make sure I get in all my protein in a day. It's to the point where I want to fast for a day or two just to feel empty.  Has this happend to anyone else?

Yes, and I also began to notice I wasn't  having the normal BM. Then I started having a stomach ache. This lasted for a while until the pain became unbearable.
ER, CAT scan, and I found I had a partial bowel obstruction. Not suggesting this is your problem, but if it's lasting for a long time, think about the whole picture, and maybe you need to see a doctor.
Good Luck!
