Anyway, good luck man! I hope you at least got one of those n95 or kn95 or some sort of 3D shaped masks so that at least your nose and mouth are not constantly rubbing against something as with surgical/cloth masks. Plus, n95 should be safer too.
The most physically challenging part for me besides getting dehydrated was that my ears were also hurting. Thanks to WFH for so long... I never really had to wear masks for so long until my ears began to hurt! This is probably like getting a new pair of glasses... ears take some time to get use to it...
