Thanks for your reply
I have decided to give it a go, but I can't attend for the next couple of weeks.
I've got a voucher from my local paper giving me free membership so I will only pay for the class itself, so at least that way I can give it a go without paying out too much.
I feel that what I'm doing is working quite well, so although I'm prepared to take on board the "diet plan" they offer at the club, I think I will "adapt" to fit in with my counting cals anyway, as being flexible helps me to stick with it, so some days I only have 1100 cals and another 2000 - it works for me.
So I'll give it a go, get some info, some recipes and ideas perhaps, some exercise and maybe make some friends too. Like you say, it all depends on the instructor, if I don't take to her, then it's not going to work!
Thanks
