@4aces4me my first was the at home under Dr. Roy in Huntsville. Sketchy as heck operation and phone call with “results” they seemed less than professional and suddenly they shutdown last year so this was my second go at it one week ago Friday at Huntsville Hospital sleep lab in Madison. Much more professional operation. I’m just not overly confident in Huntsville Hospital, thus seeking reviews and others experiences at UAB And Vanderbilt.
