Can't Live Without It

I'm currently reading Judith Levine's Not Buying It: My Year Without Shopping an account of a year spent buying only essential items. She begins by making a list of those items that she cannot function without. Her cat is diabetic so insulin is on the essential list. But other items, more life enhancing than absolutely necessary, make the "can't live without it" list.
That prompted me to think about what I consider "essential" to my life on this planet, and later I started to compose an essential shopping list for this weekend. Here it is in all its hedonistic, alcoholic glory.



Don't judge me too harshly, Levine's last purchase before giving up consumerism was a concrete baby elephant from Red Envelope.
Apart from insulin and related items like syringes (not much point in having insulin if you can't find a way to get it into your body) and your loved ones, what are your "must haves" to sustain body and soul, if not for twelve months then at least for the next weekend?
