The only mistake you're making is that you are drinking it undiluted which is dangerous for your throat and stomach. Warm water, 2 teaspoons of apple cider vinegar and a few drops of honey.

ACV helps prevent my sleep apnea. I would stop breathing while falling asleep, didn't matter of I was lying on my back or on my side. It scared me so much, because I could feel it happening and would be struggling to wake up and breathe again.
I'm a 42 yr. old woman, I'm overweight but have lost quite a lot of weight the past 6 months after switching to low GI foods. I'm generally healthy for being a big girl. My dad suffers from severe sleep apnea, and I've inherited snoring from mum's side of the family. Mum also has high blood pressure and heart rhythm disorder, and I've had high blood pressure and heart palpitations in the past when I was 20 kilos heavier than I am now.
I work irregular shifts and was using natural melatonin in a low dose (0,1 mg) to regulate my sleep, but I recently found out that when I didn't take melatonin, the sleep apnea didn't occur.
So I stopped using melatonin. I sensed my blood pressure was running a bit high due to stress and I started to take one or two tablespoons of unfiltered, raw ACV, straight from the spoon, before bedtime and before brushing my teeth. I don't mind the taste and have no problems swallowing the ACV quickly.
Haven't had any apnea since then! No more melatonin for me, ACV it is.
