I don't drink often at all any more, I'm not tee-total but I don't drink "for the sake of it", occasions only (although the occasion can be as simple as a meet up with old friends) but can answer from days gone;
As a teen I was a strict "Friday and Saturday only" drinker. Mainly because I've always been awful/non-functional on a hangover and I quite liked school, so I would always turn down ill-advised weeknight plans. Similarly, I wouldn't drink for any reason these days if I had work the next day... because I'd end up simply not logging in.
Uni on the other hand

was a free-for-all. Generally didn't drink on Mondays and Tuesdays just because they were dead nights, but Wednesday was the biggest student night of the week so any night from Weds - Sunday was fair game.
I went through a roughly 3 or 4 month phase in first year where I was drinking Wed/Thu/Fri/Sat pretty much every week and I ended up really unwell. Lost over 3 stone and was crapping blood
a lot. I was in a fairly self-destructive or, at least, totally nihilistic phase... to be fair... if I was losing weight like that now and pooping blood constantly I'd be panicking about cancer or something but I just didn't give a ****.
Anyway yeah... not to moralise, but I would ultimately say, no I don't think drinking regularly through the week is a very healthy adult decision.
