Struggling with Blood Sugar While Dieting for Diabetes

I was dieting pretty well earlier this year before stopping due to circumstances, but when I was dieting I seemed to have no problems with my BG and my A1C dropped to a 5.2. I want to diet again to lose more weight, but the thing is that recently, every time I try to eat less, my blood sugar drops multiple times a day and I'm forced to eat something sugary and high-calorie to raise it again. I tried cutting down on my meds but that only ended up making me feel awful due to high blood sugar. Even if I tweak my meds downwards the tiniest bit, I end up having an average BG of 200. So I'm not losing any weight because every other hour I'm eating candy and drinking juice to raise my blood sugar. Does anyone have any idea how to combat this?
