I'm an 18 year old skinny fuck at 5'6" and ~150 lb (haven't weighed myself in a bit). I've been bulking near constantly for the last year or so except for this summer where I just ate at maintenance for a few months like a pussy. I started at 115-120 lb. Overall I believe I've gained close to no fat at all. Possibly even lost a little over the summer.
Anyway, for the last two weeks or so I've had a bit of trouble getting in enough food. I've started feeling like you feel when you've just started bulking. The nausea threshold is way closer than it was just a week or two ago. Also I'm not hungry in the evening, even with just one meal since the morning. (A 1500-2000 calorie meal, but still) It used to be that I'd feel full for about half an hour, then I'd start feeling hungry again pretty quickly. Feels like my metabolism is slowed down a bunch.
Two things that could have something to do with it. The last few days I haven't been training quite as hard as usual, as my body's starting to get a bit unhappy. I guess you could say I'm deloading. Also I haven't been sleeping quite as much as I ought to.
So given all that, I'm wondering whether I should keep shoveling in the food and suck it up? Or should I listen to my body? I'm leaning towards shoveling it in anyway, but I tend to make bad decisions in terms of knowing when to let up a bit for the sake of the long term. I'd appreciate any advice from more experienced lifters. Thanks for your help and sorry for the super long post.
