I would avoid it..Etiz is not generally fatal by itself, but when mixed with other depressants, especially alcohol you may end up dead. Or at least messed up enough to get into deep shit.
A recent example. I popped 4mgs of Etiz last week for a long haul flight, over 10 hours. When the stew came around, I asked for a gin and tonic. At dinner, I had a glass of wine.
I walked off that plane with a huge wine stain down the back of my pants and all over my jacket. I and I NO RECOLLECTION of what the heck happened. That is the scary part. Something must have taken place, but I don't know what. For all I know, I could have began singing and dancing in the aisle and then have woken up in an airport prison.
Seriously, for get the booze. Etiz on it's own is plenty fun. So is booze..but putting them together can kill you.
