I'm not at all an expert, but I have some notion that going from lifting very heavy weights for few reps to lifting slightly less heavy weights for more reps might be helpful (if you can lift at all - I've no idea what BPPV is but rotator cuff damage isn't a good thing, I do know that). (Apologies if that's really obvious to you!)
I've read "Racing Weight" mentioned above - you'll probably feel it doesn't talk quite to where you are, but the advice in general is good.
