Coke these days varies so greatly.. most of the time you really don’t know how you are going to react. Take a little, which of course is tough, and see how you feel. Really good clean blow shouldn’t raise your heart rate that much (unless you smash a G to the dome). Wait 15-30 mins, and do a little more. End the evening with a Xanax, or better yet, liposomal magnesium. Magnesium is what they would give you right away at the hospital if you went it.. the stuff is magic. I take 1300mg after my last bump and can fall asleep no problem within an hour or so. Hope this helps. Benzos of course feel good, but we all know benzos and opiates suck. I like my brain (most of the time) the way it is.
