I'm on my preop diet right now , only 3 days to go ! I haven't cheated yet I have gained 5 lbs then lost 4 of them , I am swollen and my eye lids are puffy . I'm really feeling bummed bc I know this is my journey but I've never read anyone else say they've gained weight on a clear liquids with protein shake diet & to top it all off I'm working out 4-5 days a week . Any advise ? I'm really feeling down right now when all I should be feeling is excitement .....
