That's interesting advice, and good to hear. This post is actually quite timely as I've been feeling very demoralised lately about my activity levels.

This past Saturday, I was feeling "ok" in the AM and thought it might be a good day to hit the treadmill. Over the past year I've tried it off and on with all negative results. For this session, I walked 3 min at a slow pace and 2 min (total 5 min) at a normal gait. Within the first 30 sec my headaches increased; by 3 min I felt different, and by 5 min I knew I had done way too much.

From this relatively benign activity, I have been recovering for the past 3 days in which I've had progressively worse symptoms, including intense headaches, frustration/anger, rumination, and the need for isolation. Based on my experience, my symptoms will platueau for a day or two and then taper off over the following 3-4 days. This recovery from a 5 min walk seems ridiculously disproportionate to the activity level, but it's what I experience regardless of activity/stimulation.

I like what Mark says about learning to recognise your queues, but for me the index between ok and over-stimulated is insanely narrow.

In the end, I am so utterly frustrated and demoralised with my intolerance to activity. Miller, if you can post your progress through this I would greatly appreciate it. I recently said to my wife that if I knew it would make me better I'd get back to running again, issues be damned.
