Thanks IngeA. That's really encouraging. I've been going to the pool 3 times a week for the last 3 weeks or so, and at the very least I definitely feel more comfortable in the water.
I've just bought the downloadable video series for "1.0 Effortless Endurance Self-Coaching Course" so i can review the videos before i go to the pool. I'll spend some time on balance and getting the basics right - at least i'll try.
THanks for the encouragement all.
