Overeating After Fasting

I would like to do a water fast for healing and weight loss. However, I fear the inevitable extreme need to feed after breaking the fast.

I've done two 3-day water fasts in the past 2 years and both times I have a few days that I do really well eating small amounts and not wanting more, but then after about 5 days I get incredibly hungry and all I want to do is eat.

My thought patterns change into only wanting to eat and take over. Then I ended up overeating to nausea.

I don't want to start a fast unless I know how to deal with this. Any tips?
