Improve sleep tracking accuracy

Sorry if this is against the rule of the sub I recently severely cut back on my alcohol consumption (from 4-6Liters of beer per night to 500ml or 1 tall boy after work )and my sleep quality has went down whit it or at least it feels like it , been about 2 months now (This is before reducing my alcohol consumption) Before I used Snore lab for the snoring part but after switching to a Samsung phone it would record random stuff like moving in bed , my Ac turning on or my dog walking around as severe snoring , stopped using that after a month of the nonsense Also tryed the Samsung sleep tracking thing + a smartwatch that went from completely wrong , giving me excellent sleep when I woke up feeling like shit and poor sleep scoring when waking up fresh , whit the same random recordings Ac,dog, sheets moving around to giving me somewhat random scoring after like 2 months of use but still mostly wrong , stopped using that as well After cutting back on the alcohol I went from needing roughtly 6.5h of sleep to feel fresh to being grumpy after 8 or more hours of sleep
