Having flown C172's for the last three years in IMC almost weekly I can say the best thing to do is not think about it!
No seriously with 2000 hours on type about 600 of those IFR never had a problem, thats not to say I never will.
I think the thing that stands out here is that your position should be crystal in your mind relative to vfr map, I never fly without a VFR map tracking my position continuously and always use a RIS, RAS if available, NEVER NEVER scud run.
Another point to consider is what assures you that two engines will make it any easier, at all up weight some twins, regardless of what that magic book says will not give you a climb to clear obstacles in flight path. or maintain level flight.
"sometimes 2nd engine takes you to the crash site " to quote a CAA examiner.
