Tom,
This "habit" of yours is escalating at an alarming rate. You are now getting "fixes" up to four times a day. I find this to be troubling and that you may need an intervention. I hope your family is up to the task. The "Equine Element" in this farce is most disturbing. Your correlation between Horses and your "fix" is not unheard of, but this symptom can be an unwanted marker of future unhealthy behaviors that cross over into other genus's.
This issue may also push your follow up work on your ground breaking thesis published by the University of Wisconsin - Madison "Agriculture & Applied Economics Department" concerning Sunglasses, Chickens, and their Weeding Potential with Ornamental Plants. We in the Iris community are waiting with much anticipation on this new work. and any delay would be very detrimental. There are many reports of "Bermudafication" happening in the Iris community and your preliminary tracks for the follow up work hinted at a remediation in the "grasses" area.
Please get the help you need so we may live weed free and employ our under employed avian workforce.
Please let me know if I may assist in any way (such as a garden rescue to relieve you of your Iris burden). Your humble servant.
Greg
