Well, I think I figured out why I can't lose these last 20 lbs. It's basically my insomnia and that (due to working from home) I'm sitting at my computer too much. Even exercising and calorie restriction isn't enough.
I need to figure out how to take more walks and will probably have to go back on my lions mane mushroom to deal with my insomnia again.
