Girl, I was sleeved back in June, and after about 5-7 days I was hungry....I swore I could just run a tube down my throat and pump those liquids in cause my arm was so sore from lifting the cup ALL THE TIME! I'd take 2-3 sips, be full as a tick on a fat dog........and then 5 minutes later starving to death!!!
My surgeon laughed at me (for some reason, I get that response a lot) but encouraged me to keep drinking and sipping, things would even out........and they did.
And maybe all that lifting toned up my biceps a little too.
