Going low while sleeping

I’ve been T1 for about 6 months, and since I’ve been diagnosed I’ve consistently had the problem of going low while sleeping.

I’m currently using Tresiba (give in the morning) which has been better than Lantus, but usually around 1-3 in the morning I’ll go low for about half an hour (I’m using Libre so I don’t get any alarms and just sleep through it).

I know the solution to this would be to decrease basal, but I’m only on 5 units and based off my blood sugars during the day, I think I need more, but I can’t go that cause I’ll go even lower at night.

Any tips? I try to eat snacks before bed (10-15g carbs with almond butter or nuts) but I HATE eating right before I sleep. When I eat snacks I usually stay steady in the high 4mmol/L, but sometimes I still go low 🤷🏻‍♀️🤷🏻‍♀️.

It’s really annoying because I KNOW I need more basal during the day but I can’t do anything about it!!!!!!!
