Two or three days when I got my first five string. My four string was a piece of crap and I needed something professional and reliable. It just so happened that my first "good bass" (after years of playing on the old POS - I should not have waited so long) was a five string. A gig came up suddenly and I needed a good reliable bass and my POS was not it.How long after adding another string to your playing did feel comfortable enough to gig with it ? I think I had my first 5 string maybe 2 or 3 weeks before I took it out live.
