Ashwaganda causing low blood sugars?

I'm prediabetic with an A1C of 6.2 or thereabouts. As an experiment I took 1 450 capsule in the am and 1 in the evening. My morning fasting blood sugar went from an average of 108-112 daily to 100-101-101-96-104-96-89 this am. Perhaps you took too much and should cut back to one. Everything I've read said it's relatively safe for up to 3 months and may cause liver damage in some. Nothing says how much. But I've noticed up to 500 daily is sometimes mentioned. I'm concerned about liver damage. So I'm cutting back to 1 at night because it's also said it can make you sleepy and I'm an insomniac. I think it does help my sleep so my preference would be at night for better sleep and better fasting blood sugar. It's also supposed to help with muscles and I lift weights several times a week and I also have GAD and occasionally take a Xanax. I felt less anxiety and worried/depressed and cranky during the week and was willing to go out more. I wish this was safer re the liver, I'd definitely take it 2x a day until my fasting blood surger and hopefully A1C went into normal.
