I'm on day 4 of 7 pre-op. I am crazy hungry, super weak and have a cold! It sucks big time but remember, the better you do pre-op the easier your recovery will be post-op! Shrink that liver baby! I go in Tuesday for my surgery!!! I also had headaches, my surgeon said extra strength tylenol was okay since it's not an NSAID. That has been a life saver... and microwavable dinners for my kids! Then I don't have to stand over the stove huffing the aromas like an addict in withdrawl!!! I cheated on Halloween had some bite sized chocolate. Felt TONS better the next morning but it just restarts the whole cycle and keeps you miserable I think. We can do this!
