Well, I personally think you don't necessary need it every day again but it would certainly be healthy to get that amount of sleep as frequently as possible. So, I think it would be ok if you tried MILD on days where you know nothing important is happening or you know you can sleep out a little longer in the morning. But certainly not everyday, no.

But yeah, consider other methods as well. But if you really feel MILD will work best for you, I'd take it easy and not overdo it too much
