Congrats Colin - that's a great plan!
Anyone who's ever lost a good amount of weight or has had a good amount of weight to lose can totally appreciate the effort it takes to stick with something.
My daughter and I started walking every morning last week - we do about a good hour of brisk walking (without the dog - that totally breaks up the pace we found) and started doing laps in the pool at night. It really gives you a lot more energy - and hopefully we'll start seeing results soon
I did really well on Atkins but it's SO hard to stick to for a long period of time... we learned a lot about what to eat and what NOT to eat so it was educational... but hard to stick to 100% IMHO.
CONGRATS to all who have posted here about losses. Keep up the good work!
