AB.....you're at 180lbs now? How tall are you? I remember from your vids, you look pretty lean and trim.....unless you want to get to sub-10% bodyfat (unless doing a BB show, I don't know why on Earth you would), dieting doesn't have to be a progress-wrecking thing.....if you feel you could be leaner, you can just trim the edges and restrict cals a little by doing things like stop eating after your post-workout meal (so long as u work out in the evening, lol), if not then just stop after dinner........really though, you look like the kind of guy who even if you were in a pinch (date at the beach with a girl next weekend) you could get as lean as you'll ever need to with a good week of watching cals, don't make it so uncomfortable on yourself.
And, if for whatever reason you want to keep dropping weight, then don't be hard on yourself and look at it how it is....not too many guys over 5' 10" who weigh less then 170-some pounds are gonna be really strong, there's no way around being human.
Good luck though, I hope you come back rested up and ready to go.
