I've done it in the past, but thankfully not recently. Ever since I stopped drinking and smoking weed, I've been 1,000x more stable.

When I was IP, I had a nurse who talked about this stuff. She said that in an over-simplified way of thinking, the alcohol and substances compete for the same receptors as the BP meds. They bind faster and tighter; therefore, if you're drinking and drugging it's basically the same as being "off your meds." I hate that phrase, but based on personal experience it seems she was right. I know it's not perfect neuroscience, but it works for me.
