Whenever I get into one of those moods, looking at ebay or B&H or KEH website and dreaming, then I'll always wait 24 hours before I pull the trigger. Ninety nine percent of the time the madness passes. My therapy has been shooting 4X5 on paper negatives. You need only minimal equipment, a cobbled together 4X5, a few holders, lens from an old Kodak 1A, and a set of 5x7 trays. Slow work at ISO 6~12 and quite relaxing, to me anyway. To be fair I already had all the paper and chemicals and trays and a dark place to screw in a red safelight.
Another thought. The finished product is something you can hold in your hands. Not some 1's and 0's stored in memory until and unless you print them out.
