One of the things my neurologist has mentioned is that the damage from a concussion is measured by the initial hit, or any other sub-concussive hits.

I am wondering that since I was able to recover from my latest subconcussive hit (including use of alcohol as a sub-concussive hit), but had several full setbacks due to overstimulation, latest one about three months ago, would the brain continue to heal, albeit at a slower pace now?

The last time it took me about 45-50 days after my setback to start feeling any change and improvement in thinking. But, after immediately overstimulating I have not felt change in the last 80+ days. I know it's stupid to put any kind of timeline on this stuff because all it does is lead to higher anxiety, but would love to know the answer to that question posed in the previous paragraph, as it would really help ease the anxiety despite these terrible headaches. I guess I should mention that I have been dealing with my last sub-concussive hit in July 2015, and have been going in circles of recovery and setbacks since then.
