Once or twice a month my Forerunner thinks at 00:15 (after I do my daily breath exercises) I'm not going to sleep anymore. I get the awakening screen allready. Clearly I have to go to sleep yet. It would be nice if there was a feature when you could toggle sleep mode on (or off). Cause now it doesn't record my sleep (and hrv) from that night. Very anoying. Turning the watch off and on again doesn't help. So please give us a feature to toggle sleep mode on and off. It also happens a lot it falsley turns on when watching the tv on the couch. Must not be to hard to make such a feature.
