u/Balthasar-Hohenheim

As written in the title I'm searching for a sleep physician/doctor that is specialized or at least knows about DSPD. I'm trying to get an official diagnosis and ideally help with stabilizing and advancing my slightly erratic sleep cycle (2-6am to 12-14am).

The problem is that seemingly all German sleep doctors are purely specialized in snoring (most are either dentists or ENT specialists) and I have yet to see one that even mentions circadian rhythm disorders (let alone DSSP) on their website.

So does anyone here know a good specialist in the Frankfurt/ Wiesbaden/ Mainz area of Germany that they are willing to share?
