loopy pretty much the same happened to me and "propelled" me into retirement. Here's what I have learnt: you spend a lot less money when you are not out and about. I am at home day after day quite happily and sometimes my only spending is on bread and milk. Compare that to popping in to somewhere like Pret daily for lunch (in London).
After about a year of full time retirement I got a bit bored so I took a short term contract which ends in June - only accepted it because interested me. So I'm already looking forward to having the summer off again. I only work 3 days a week (from home) - and on the other days my best is settling down with my knitting to watch a movie at 10 a.m.
Now when people ask me "Are you retired?" I say "No, I'm in transition". 
Good luck!
