I keep toying with the idea of seeing a sleep specialist and going to a sleep clinic. I can't make my mind up. I would like to know if going to a sleep clinic has actually helped anyone or do they just measure sleep apnea? I went to a sleep clinic 13 years ago. They expected you to sleep from 8p.m till 6 a,m in the morning. I have delayed circadium rythm so I only fell asleep at 4a.m. They told me it was not enough time, diagnosed delayed circadium rythm. They then told me to take melatonin and come again. I did not return because melatonin does not help and the sleep clinic doctor was terrible. I am thinking of trying again with another clinic, but have been told that all sleep clinics only check for sleep apnoe. Is that true?? Has a sleep clinic actually helped anyone?
