i know what you mean, I just cant get myself out there jogging when it's dark and cold : walking is a bit better for now, and to get myself more prepaired for jogging (or so i tell myself!)
I am hoping I will do it again, I had to change my whole life and ideas about food etc, and I think if you do it the first time (which was soooo hard at first) then I am hoping the next time won't be so hard because you already know the things you had to learn the first time around. I think cutting sugar, caffine, and carbs down is the hardest since the body gets 'addicted'.
I can't do the gym, I'd rather do my own exercise for next to nil. I can't afford it now anyhow, would hate paying for something I didn't use or might be uncomfortable or self concious with. But that's just me, I have friends who love the gym and swear by it.
Let me know about davina's dvd, a lot of people like it, but there's just so many exercise dvds out there it's hard to choose!
Good luck x
