Hi guys I'm from Denmark, and I'm thinking about getting the watch when it comes out next week. I'm still not convinced, but one the things I like is the way the watch can wake you up with small taps on the wrist. It's just that as far as I can see, sleeping with the watch is sort of problematic because of the battery time. I have been thinking, that I could sleep with it, charge it for 20-30 minutes in the morning and then fully in the evening again. Do you see any problems with that? And what do other that sleep with the watch do? Thanks!
