I wouldn't worry about it hun, just kick it to the side and carry on with the shakes.. I kinda licked a fortune cookie yesterday lol. I think the best thing is to not feel guilty about it. Just know that you've had your little nibble and it tasted good and move on.. I try not to be to emotional about food.
I was talking to my brother earlier and I was saying to him that I enjoy food too much, to after this just give up everything I love and enjoy, I'm just going to be more sensible like instead of having a whole 10" pizza to myself with garlic bread and onion rings just have what I need to fill me up.
We've got to remember that we still need certain foods to enjoy our lives after this process.. If that makes sense lol.
Goodluck with the rest of your week xx
