Dr Kristo was kind and gentle. His student was also wonderful. I appreciate their time very much.However, I, too, am a medical professional. I knew just about everything Dr Kristo had to say. I learned nothing.I walked away from my 120mile drive being told to go to bed at the same time every day. I have not slept through a night or day in 17 years.I will definitely be trying to keep a better route for my sleep hygiene practice, but I'm quite disappointed there was nothing further to be done.
