Look into weight gainers, and try to eat a peanut butter and jelly sandwich before bed with a casein shake every day.

You will gain some solid mass on GOMAD while lifting heavy...or entirely the wrong kind of weight if you don't lift at all. Regardless, look into it.
Thank you for your input! I realized just a few days ago that I should've been putting regular milk instead of almond milk in my protein shakes this entire time....whoops. You live and learn I guess...
I bought a pack of chicken breasts yesterday and have been eating one (cooked, obviously) every 2-3 hours, along with a glass of milk.
