I can feel the fatigue lifting, and gave some hope for the first time in a long time

I've been on HCQ for about 3 and a halfish months now. I noticed a couple days ago that I didn't feel so run down. I have actually been keeping up on things that need done instead of putting everything off until the last minute. I haven't been randomly falling asleep at odd times. Today I had to teach a particularly boring class, it was 8 hours of dull videos. I had the lights off so the students could see the screen better. I was bored out of my mind, and I didn't fall asleep. Just a few weeks ago I could barely hold a conversation without dozing off. Any lull, I would immediately start nodding off. Literally all of my energy was used to stay awake at work so I didn't get fired. Today when I got home from work I got a head start on my weekend chores. I just absolutely can't believe it. I felt so hopeless and now I can see light at the end of the tunnel.
