Need Energy!!!

Hi can anyone help with a supplement or something that helps with energy after WLS. I had surgery in March and still not eating much. Is there a supplement that I can take that will help with energy??? I have lost 136lbs and feel good but no energy. HELP!!

Can you drink coffee?

1/2 cup half and half (or any kind of milk or water if you want)
2 scoops chocolate or vanilla protein powder
blend

add coffee (I do 3 cups on the side of the coffee pot)
ice
blend.

omg. SOOOOO GOOD.
