It looks like you found out the utility of employing deloads or at least periodizing your intensity. This is what you're essentially doing. It gives your whole body (neuromuscular system and soft tissues) a chance to recover from heavy training.

Deloads can last anywhere from 5 days to about 14. Any more than 2 weeks is not suggested as you probably start losing a good deal of conditioning at that point (not talking about gaining fat, I mean your strength and speed start to plummet).
What you do during that week or two is up to you. You could do what you would normally do minus all heavy lifting. You could most of your normal, heavy lifts, but cut the reps back significantly (instead of a max of 3, do a max of 1 with that same weight), and cut down the volume of your accessory work. You can switch to doing high rep work with dumbbells, for instance, working up to sets of heavy 20s until you can't do more than 20 with upper body work, and do unilateral leg work for leg days also using dumbbells for higher reps (10-20). Don't use any accommodating resistance, though (like chains and bands), unless the bands are helping you lighten the load at some portion of the movement for things like pullups or glute ham raises.
