I would give up the drinking to be frank. Drinking is not good for a non injured brain. For an injured brain it's terrible. To have the best chance of a good recovery, you need to get your brain to a point where it is symptom free, the longer you can avoid your triggers, the quicker your brain will recover when in this state. Push it, and you'll suffer set backs which can last weeks or months. I've been there many times.

Being sensible about avoiding triggers with pcs and having a positive attitude helps the most. And not hitting your head again helps too!
