Jeff, this is where it's always been do or die time for you. Right at about 175.....you're a little less depleted and starved down and you start to freak about not being dry and crisp, but look at it this way, do you want to be dry and crisp at 160? or at 220? The choice is yours, but if you ever want to stop going around in circles, just suck it up and keep going.
Also, it's Sun, eat something that tastes good. I also think mental burnout and feeling like life sucks would go away if you cut back lifting to 4 days a week, and didn't so much as drive by the gym on your 3 off days......it's the peak of tax season too, so it's not like you've got time on your hands anyway.
Put that tuna on 3 slices of WW bread.....and add some yolks to those eggs, despite the scare tactics yolks are the ''good'' cholerterol......you'd be surprised at how satisfying 4-5 whole eggs are compared to 12 whites.
Take a page from Bruce's cook book. He eats pretty similar to me, which I thought was pretty cool to see on a ''bodybuilding'' board. I need to slap on 15lbs myself, I'll try to think of some high cal recipe ideas.
