I tried Ethanol 96% intravenously. And it was a bad experience. DON'T TRY to inject undiluted ethanol. Pure alcohol has antibacterial properties and it instantly leads to the death of leukocytes and creates a blood clot in the vein. Perhaps this blood clot could cause a heart attack. But in my case, I just blocked my vein. Also, I'm not a doctor, when I tried to put myself on a drip, not the first time I got into a vein. And the introduction of pure alcohol under the skin leads to terrible pain. And also to a huge hematoma and necrosis.
But, after a few weeks, everything healed by itself. Without medical intervention. Fortunately, when I saw how much the vein began to swell, I stopped the drip.
After an unsuccessful attempt, I thoroughly googled this method. And it turned out that it was necessary to dilute alcohol, otherwise there would be a blood clot.
If you decided to try, you need to dilute alcohol to 20-40%.
