Thanks for the response and your time. OK, here are some of the activities I've been doing while trying to quietly rest.

Play solitaire, backgammon, etc. (sometimes exacerbates headache)

Shuffle cards

Sit quietly outside

Meditation

Reading (A month and a half ago I was able to read a full New Yorker magazine without exacerbating symptoms, I've since cut back dramatically as shorter reading bouts seem to exacerbate symptoms more easily now)

Listening to audiobooks (Just started this today actually, hard to know what effect it's having)

I'm thinking of trying painting - never done it, but might be relaxing

Computer work (Trying to not let emails and contact with the outside world completely go, I should be more diligent about limiting this)

Listening to music (usually classical, generally seems OK, although sometimes exacerbates headache)

Conversing with friends and family (rarely exacerbates headache)

Cooking

Walking (1.5 months ago was doing 30-40 minute bike rides, back to doing short walks, they don't seem to make the headaches much worse, but sometimes they flare up)

I've been trying to generally do a 2 hours of "activity", 30 minutes of rest (i.e. laying down, icing neck, etc.)
