When I can be bothered to go swimming I do sets of 5 front, 5 breast, 4 back and 1 'fly if there is space to do it in (because, er, I'm really really bad at 'fly and make lots of splashing etc.).

I should really find time to go swimming more often, I'm not sure how much useful swimming I could fit into lunch break though (and is the pool open for normal-people swimming after 5pm?).

Prescription goggles... where did you get them?
