Hi and welcome,
If your sugars have always run in their 20's then dropping to 5/6 then you will get these feelings of hypo. If possible try and see if you can keep the same lower levels and it will eventually settle.
I know it's hard but keeping your sugars at a high level can lead to complication, which you really don't want, ( i certainly don't want to worry you) but i do have some complications and wouldn't want it happening to you.
If i can help please don't hesitate to contact me.
Good luck and take care
Tracey
