@sunspots I'm not sure if you are being serious here. Alcohol is the worst way I can think of for lowering BG.
At least Berberine products (some of them), correct type of cinnamon (I forget which but apparently a common one doesn't work), do it without the potential problems of adding high calories, affecting judgement (it only takes 1 unit of alcohol to affect it), putting liver under pressure, getting drunk etc.
Which remedies did you try for 'Keto Flu'? I went Low Carb but never Keto, my BG levels just flirt around actually being in Ketosis each day.
The things I did were:
1. Drink plenty of fluids carbs retain fluid so when people go low carb/keto the pee out fluid quicker 9along with electrolytes) and so can get dehydrated more easily.
2. Take electrolyte supplements (though others find bone broth works well instead). I use lots of 'reduced Sodium Salt' This keeps both my Sodium and Potassium levels good, then I take a Magnesium supplement. My personal choice is Magnesium Glycinate (because it also helps with sleeping disorders) the cheaper Mag Citrate would give me looser bowels, which I don't need - LOL!
