Mixing anything with alcohol is a really bad idea. Abuse of deithylprpion seems to be newish. Why chance it? Alcohol isn't even euphoric, not compared to opiates and stuff like that. Since it is a phenethylamine, I'm just going to share my experiences with amphetamines with alcohol in general...
It makes you drink more, pass out later, and do stupider shit cause you think you're not as drunk.
Will you die? Probably not, but it's a combo with absolutely now reason to mix.
It's really smart of you to ask before you do it. It's the right thing to do. By asking this question, you might have saved your life.
Stay safe.
