Hi love,
Your fear is totally understandable!
I have an almost phobia of the lows. They are so unpleasant, and make you feel so helpless.
But it is a fantastic sense of relief when you find ways to stop them.
Like getting your life back.
Treatment depends on the severity and cause of your RH.
I was always able to keep things under control if I stayed on a low carb diet (which I didn't, all the time, because I didn't really know what I was doing back then)
Others, like
@nosher8355 are on medication, but I've no idea what the meds are... Maybe he can explain.
But I know that he relies heavily on diet too - it really is key.
Have you found the low carb section of the forum? Have a read. The trick is to avoid any foods that raise your blood glucose quickly (like bread, rice, pasta, sugar, fruit juice, sweet fruit, sweet drinks, potatoes) and replace them with slower release foods like non-root veg, berries, cold meats, cheese, nuts, cream and butter and oils.
Next time you go to bed, have a small snack (nuts, cheese, cold meat, no carbs) before bed.
It will dramatically reduce the odds of your 3am hypo.
And regular small snacks of these slow release foods, through the day, will also stop the hypos from developing.
My danger points were about 3 hrs after breakfast, and 3 hrs after lunch.
When I switched to bacon and egg breakfasts, and a mid afternoon nut snack, they virtually disappeared!
Hope this helps!
