@nuala cold showers TERRIFY me but they seem quite common among decaffers, I guess because it triggers fight or flight or gets the blood pumping or something? I'm one of those folks that, given a shower I'm not paying a quarter a minute for, will happily stand there for 30+ minutes melting my skin off (poor water heaters / environment...) because I just love hot showers
that + ramping up more spicy meals might be worth a try rather than just throwing in the towel, thanks for the idea.
