I agree regarding day 2 onwards - the main problem is if anyone else in the house (rest of the family) is cooking, as the heightened sense of smell brings in psychological hunger.
I agree; I try to go out and have a small walk if someone cruel is having curry or anything else strong :-)
Also, I'm lucky that I have a separate 'lab' building where I can go and do some hacking during dinner, most excellent excuse to go spend some time with the CNC or 3d printer :-)
