I have been getting severe calf cramps in the wee hours of the morning. This normally happens when i vape a lot the night before. Is there any other way to prevent this from happening? I have hypertension and when i get these cramps while I'm sleeping, I wake up in a shock and I'm worried if I would blow a blood vessel or have a heart attack when i get these cramps. I am an ardent vaper. I vape till I am about to sleep. Is there another way to go about this other than to vape less?
