I had a "mild" concussion only but the first few days were pretty rough and it's taken me a while to recover (I'd had at least one concussion before, maybe 2 or 3). I've had a couple of minor setbacks and one more significant one (the latter resulting in some apparent tinnitus that has yet to go away). I'm now at the two-week mark and feel a lot better, although I have yet to really push the envelope with activities.

This whole process has been mystifying at times, but the things that seem to have helped the most are: (1) tons of physical and mental rest and "non-doing" (I'm on short-term disability and will be off work for at least another week), (2) good basic nutrition (not skipping meals, minimal caffeine, no alcohol, a healthy and varied diet), (3) *minimal* exertion (I'm gradually starting to do more around the house and introducing slow, short walks outside), (4) avoiding too much time on the computer / cell phone, (5) no TV, (6) support from family - I'm currently staying with them - and from my significant other and a few close friends (this can be a simple as an email, short phone call, brief visit, or sharing a meal), (7) seeing a good concussion specialist, (8) practicing mindful breathing to fend off anxiety / depression, (9) talking to a good therapist / naturopath by phone for 20-30 mins once a week, and (10) reminding myself to be patient (easier said than done) - it takes time to recover from a head injury, no way around this.
