I try to keep my addictions in check, but I do have a healthy instrument collection, particularly guitars. I have a pre-war Harmony jazz guitar and a fretless Wish bass (handmade instrument, I've replaced the pickup, but still needs more work). Just cracked the neck on an astounding cheap acoustic/electric that I'll need to replace (SX DG-25. Bought the 12 string version that sounded WAY better than it should for the price. Bought the 6, which was a bit more like what you'd expect, but put a lot of work into it and got it sounding really good. Any acoustic film work I've done has been with that guitar). Most of my collection fits different niches and all of it was acquired dirt cheap (most expensive guitar was $250 on an Epiphone SG custom that retailed for $400. Cracked finish, so I got a deal on it)
My music collection is pretty diverse and has some pretty rare items (several limited to less than 20 copies), but it's all weird stuff that most people wouldn't know or care about, so there's that.
I drink a lot of coffee, but spend a couple weeks every year without to keep tabs on my addiction. I drink a lot, but only really one day a week, so it's not as problematic as it could be.
