Day three - T-break after 7 years of everyday smoking

I slept day one off.

Yesterday was rough - Blinding headaches and severe irritability.

Today I'm dealing with another problem: I have absolutely no appetite. I haven't eaten anything since my break started, and I still have zero desire to do so. If this is the same by tonight, I'll probably force some food down, but this is bothering me a bit.

Any other ents have this problem before? Anything that can be done?
