I've heard a number of people say they don't get the same effect from vaping so that's not surprising. Edibles should kick in within an hour or so (and better if eaten with a higher fat meal), so if they didn't they might not have been strong enough. That, however, it hard to believe if one hit holds you for 8 hours!
If you like this strain as your daytime meds, then letting some buds go much more amber is worth a shot, though I don't think any strain that gives you a head high with the giggles is going to be quite the ticket for sleep just because you let it go amber.
Northern Lights should be a couchlock high, but Haze is a sativa. It sounds like the stuff you had was leaning toward the Haze side of the parentage. If you grow clones, they will give you the same effect as the mother, but if you grow seeds from that cross you may get one plant that leans more toward the NL side (different presentations from the same strain are called different phenotypes).
