When things are that bad, attending to the urge to pee combined with a strong addiction to tobacco are probably the main things.

As one can postpone the former for several hours and the latter indefinitely, end up coaxing myself to get moving on one with the promise of the other.

Then the cigarette makes me feel much thirstier, so this motivates me to make a cup of tea. Besides, at that point am already up and half way to the kitchen, so it seems less daunting.

Getting low on tobacco is usually a good way to shove myself out of the house, and that means a good wash. Running out completely can be disastrous unless already showered & dressed, however with rollups can usually scramble together a final cigarette from unburnt tobacco in old butts & use thin notepaper if out of rolling papers.

Isn't ideal, but is what it is & whether this stuff gets me to the kitchen or out to the shops, other bits & pieces flow from there which might not otherwise.

In general, pushing myself to perform good habits before things get close to bad seems best - sleep, hydration, nutrition, personal hygiene, exercise, housework, etc., but as they all seem to evaporate as possibilities in the blink of an eye, am unsure that they actually stave off much.
