Of all the challenges I have faced on long (> 7 days for me) tours, the cumulative effects of insomnia were the most debilitating and morale-sapping. This was back when I was young and my life was comparatively worry-free. It is a significant part of the reason (in addition to breeding and blimping) I haven't done a > 7 day tour in about 30 years.

Now I am at a period where I should be able to do some more substantial rides, but my ability to get a good night sleep is at an all-time low. Even my local cycling abilities have really slipped as a consequence.

Anyone else facing this, and how did you cope?

(My touring buddy was an ER resident and then doctor, and he told me to take benadryl. I never found it worked well for me, and I was always groggy most of the next day, and highly irritable. Now there are reports of it being linked to dementia. So that's out.)
