It is ok, when i first had my surgery it took me a while before i could take in more than 300 cal a day. Your body will go into starvation mode, i did. Ketoacidosis (your body break down fat to turn it into energy), your mouth will taste funny and cottony, its a part of the process. I like tea so mint teas was helpful with the taste. Just make sure you are hydrated and are trying to drink your shakes, if you are concerned that you are not getting enough Fluid, i do suggest calling your MD. Pain is subjective everyone experiences it didfferently so never compare yourself with someone else. Take you time with physical activity, get up and walk around slowly around the block, up and down the stairs (take pain medication 30 mins before activity makes moving a little less painful). Your body is going through alot bare with it and brighter days are def coming. The full feeling will last for a while, i'm sorry to tell you, slow sips, small sips, get baby spoons, forks and plates if you had to, helps with portion control.
