Too many lows

Caprisha

So I’m having some issues with lows. I currently take a long acting insulin and fast acting before meals but at a very low dose. I always seem to have low numbers such as 45.. my lowest was 33 and it’s only after I wake up from a nap. It’s frustrating because I don’t want to eat high carb meals and make it go high. But I’ve also heard that it’s bad for it to get so low. Anyone going through this or have any advice? Thanks
