I've snored my entire life, from being a child to an adult, from being thin to being large, and slowly getting thin again.
i am a chronic snorer.
In my case its genetic, my mum and dad snore, both sets of grandparents snore, hilariously both my kids snore and my wife says it sounds just like me only mildly quieter! btw my kids are both whippets, they could probably do with gaining a few pounds if anything! so i don't think its a weight thing.
i reckon i'm uncurable. thankfully my wife has got used to it lol!
