ABs?

I've got some good abs goin...except that I often feel...I guess bloated... and my gut seems to bulge out...so it kinda looks like I have a fat stomach but it's more like my insides pushing out...I dont know if anyone knows what I'm talkin about...anyway...sometimes I wake up in the mornin and guess what...no bulging...no bloated stomach...I have my flat washboard abs again...but it lasts for most of the morning and when I finish the day...back to the bloated look.   Anyone know why this happens and how to get rid of it or maintain the flatness?

I'm Commin Back YOKED!!!

Im not sure hey, but I get the same problem. I mainly get it after eating, even the smallest meal will bulge out my stomach, when normally I have visible abs. Even when I am bloated you can see the definition of the abs bulging out! Its weird huh!
 
My amatuer theory (most likely wrong) is that because we are so lean, any amount of food or drink makes our small stomachs bloated easily....?
 
Bring on the answers...!!

im going to assume its simply water retention over the course of the day...generally you are dehydrated when you wake up giving your midsection a dry,cut look...but throughout the day your body hydrates itself and smoothes you out...thats why bodybuilders take diuretics before shows to lose any water weight and cut up.

Let the pain come over you, but never overcome you.
If you don't live for something, you'll die for nothing.

I agree with that idea.
 
But on top of that, I get a bloated stomach straigh after eating. (not just losing definition - but sticking out like a beer-belly)
