3 day protein feast-question

[Guest guest]

Hi,

I just completed a 3 day protein shake feast and it went better than

I expected. This is the first time I have tried it. I lost 5lbs and

felt for the most part pretty good. I started eating again today and

I have felt tired and more run down today than I have for the last 3

days. I am uncomfortable since I have eaten and am wondering if this

is normal after a 3 day feast. I also figured I feel better when I

don't eat and maybe I should just do shakes. Any suggestions would

be appreciated.

Thanks

Becky
