I never really thought like this, I don't look at it in terms of time, I take it a pound at a time and try not to rush.
I was at target for over 2 years then lapsed a bit and I'm slowly getting back. 9lbs to go. It's slow but I'm getting there and taking it nice and steady. I would like to be back there in a few months but it will happen.
I don't beat myself up for going out of target now, If I didn't carry on going to SW I'd have put all 3 stone back on long ago, probably more.
So, nope, I don't think it's a long way off - I'll get there. Whenever!
