In my case, the BP dropped after a few weeks. After a month and a half, I could no longer take pills that I took for almost two decades because they depressed my BP to unsafe levels (blacking out when standing up).
My fasting glucose also got lower, though it was never bad to start with. I experimented with a continuous glucose meter and I have seen about 5 per cent reduction (from 5.0 to 4.7 in Euro units).
