I don't. I've had significant problems with insomnia in the past, and in general I've found that sleep clinics really only focus on two issues:

1. Restless leg syndrome

2. Sleep Apnea

Beyond that, there really isn't much they can do besides (1) recommending standard "sleep hygiene" stuff, or (2) drugs, which all come with various tradeoffs.
