I'm in a pretty similar position though I'm nobody's idea of "the best programmer they've ever seen". I currently have a low-grade contract with some old friends. They generally accept that I'm pretty erratic schedule wise. It pays enough to help with my expenses though I'm still mostly prematurely spending my retirement. Ultimately I think the only solution for me is to get the ADHD meds, which I understand there is a shortage of now, thanks to the war on drugs or whatever, in addition to the existing shortage of doctors in my area that could actually prescribe them. Hate the US sometimes.
