How do you feel?
It is well known fact that overweight and obese people are more prone to excessive sweating as they perspire more. They have more fat tissue, thus higher body temperature, so, abnormally increased perspiration, is required for regulation of body temperature.
You have reduced your body fat weight and you stopped sweating too intensively.
So, there is no direct link between low blood pressure and sweating, but, the link goes like this: losing weight, less sweating and other link:losing weight, lower blood pressure.
I'm sure that with less kilos you are experiencing better physical and mental health.
Best wishes!
