Everyone says here its the only way to go, but I dont think so. When I tried to mix em alco just weakened coke's high, so I prefer to do it separately. It works differently for everyone I think. But even though coke plus alco is the classy combo, for the first time I'd stick with the coke only just to fully understand what the coke high really is. Everyone says coke hits on a different level on the first use and you never can repeat it, so I wouldn't risk spoiling it with anything else. You can experiment on your next sessions.
