Fatigue and weakness. Coq forte usage?

I was administered CoQ Forte tablets for general health. Coincidentally since then I had following changes gradually since then, increase in thirst and I increased my drinking levels from 1 or 2 litres intake of water to 8-10litres - resulting in frequent urination and also found myself reduction in fat levels and now I look much leaner within a span of 2 months ( reduced by 20lbs weight) and waist size reduced by 2-3 inches. I feel that whatever I eat it has least impact to increase my weight. I also found that I feel lot of fatigue and some level dizziness. I m not diabetic, i did my last regular medical check-up on dec'17 and do not have any health issues. Is it coincidental or affect of CoQ Forte usage?
