newstart_MO said:Steady state is faster than people expect: half-life about five days, so you are at plateau in roughly three to four weeks rather than five.
Sleep changes on sleep apnoea: anyone else sleeping differently? I've been sleeping more deeply since starting week 4.
My theory: the weight loss has improved my sleep apnea (confirmed by recent sleep study — AHI dropped from 25 to 6). Better oxygenation at night = better sleep quality = more energy during the day. It's a virtuous cycle.
