I just went from 192 to 181 in about 3 weeks, by tightening up my carb rotation. I gave myself about 12 weeks to do it, so I'd lose slow, but alot of it was water from excess carb intake, so it just fell off. I'm shooting for 175, and I know the last 5-6 will be slower, but I've got a few months to do it. 8 weeks is doable, if you're smart about it.
