Need "Kindly" advice (please no bashing) somewhat food/ED related

I don't have a whole lot wrong with me - no tumors or cancer etc that I know of. I believe in the therapeutic uses of fasting (even if its just to lose weight). I've seen my Psoriasis start to clear during my first fast.

However, it seems that fasting set off a 'binge' mentality. It takes over between 3 and 4 pm, and I typically am eating by the time I go to bed. Now, my 'binges' aren't 3000 cals or anything, rarely more than 1200 cals total, and I don't purge. But I can't seem to fight the 'food panic'.

I mention all this because I've been trying to begin another fast, but cannot manage to make it through one day. Perhaps I'm not sure how to mentally 'prepare'. There's no spiritual component for me. No driving medical need. Just me wanting to see the benefits, but perhaps not wanting to do the work. (And to me it is work, because I tend to get the 'false hunger' even weeks in.)

Any ideas on how to 'steel' myself mentally and emotionally? Any thoughts on preparation that might make starting easier?

Any constructive help appreciated.
