Maintaining a sleep schedule is actually awesome but you could try "pre-sleep", kinda like "pre-gaming" on a drinking night, just a biphasic sleep version. Go home early and go to bed early. Then wake up in the middle of the night to date, socialize, and drink. Then get whatever sleep you can when you get home. Worked well during the world cup for me.

I can attest to this working quite well.

On a related note: In Mediterranean countries there is often the tradition of sleeping "siesta", a short nap in the afternoon. Seems to have some use.
