Not hungry or thirsty until night time

I had my sleeve done march 5 2014. I have noticed when I wake up until about 6pm I am not hungry or thirsty. I have to force my protien and fluid, my sleeve feels like its digesting super slow. I mean a tiny bite fills me and a sip of water. My stomache isn't comfortable at all

Thn evening comes and it's like my stomache finally woke up and I am digesting liquids and foods faster. So I try to play catch up on my protien and liquids. I am not meeting either goal. 

Anyone expirenced this? Does it get better? 

Thanks for any input

I haven't experienced that but I do experience a lot of discomfort if I eat after 8 p.m. I would call your doctor and see what he thinks is going on.
