Ferret - a likely excuse lol!! Thanks to you & trogs for the earplug tips though; I normally wear them in the pool but will make sure I definitely pack them on the weekend! As for keeping relaxed & breathing normally - let's just say if any of you hear a horrid squealing noise, something akin to the noise a pig makes when it panics, early on Sunday morning then that will be me!!
Grendel - believe me, I don't particularly "want" to, but unfortunately I "need" to!!
VT - wow, good luck!! I know some lakes near me open in the evenings if that might be an option for you?? Or can you at least find a local pool that would let you wear your wetsuit for a few laps (anything more than that & you'd overheat but at least lets you give it a go...)
Buddha - I knew about the wetsuit rule temp didn't know about the water temp & distance limits, very interesting, thanks!!
