Thanks. It took about 5 months, but I feel so much better now!
I have not idea if this applies to you, but it may apply to others who lift. So I'll add just one word of caution about caffeine, as I detail in this post:

Many sports drinks contain lots of caffeine, and I remember years ago there was a trend of getting a caffeine buzz before lifting to boost performance. I tried it some, and it did sometimes help me to push myself more. However, I've learned from my recent experiences to be careful not to push myself too far, which includes moderating my caffeine intake.
