Just before (!) getting my IMC rating, I took some friends on a trip from my home field. Shortly after leaving the circuit we were in inadvertant IMC. Did the usual thing, and turned through a 180 {rate 1} and returned to the field (where we drank hot beverages until the weather had cleared somewhat.) The reassurance of having had most of the required training by then made the plan and action following getting into IMC a learned manoeuvre - rather than a panicked reaction. That was useful.
Since getting the rating flying activity has been less frequent (owing both to the depredations of my bank balance involved in obtaining the rating, and the generally mouldy weather making it not suitable to take friends for sight-seeing, etc.!) However, I did make an ILS approach to landing at Humberside a few weeks ago which was in and out of IMC. No perceived problems, so the practice ante IMC rating examination has stayed with me - fortunately.
