Breathing exercises, stretches, and self-massage are really helping my voice. Turns out my voice being damaged by reflux was really a misnomer. It was my developing (what I believe to be) muscle tension dysphonia that prevented me from talking normally. My voice has improved substantially from when I started working on it, to the point where I can actually project my voice when recording. It doesn't hurt to talk after a while like it had been for the last year. Unfortunately, this also means that I'm impacted by stress and anxiety, since it correlates to more tension in my body, but it's become more manageable nowadays.
