fuck it i'm high, drunk so have more then 10 mg of valium
Okay, one thing about mixing benzos and alcohol that it doesn't sound like you're aware of...it just causes you to black out. You're not going to remember anything, yet you can still be functional enough to walk (stumble) around and do things. This can make for a
really dangerous situation so it's best to have EITHER the benzos OR the alcohol, and not mix the two.
To answer your original question....fuck man, how long is a piece of string? It's all relative to how much you take of each drug, how long you've been using/abusing them, whether you mix it with anything else, etc.
But if you need a definitive answer, I believe that alcohol is just as dangerous as (if not more dangerous than) a lot of other drugs, including benzos, because of its abuse potential, addictive qualities, damage to the liver, stomach, brain, etc.
withdrawl is similar but more dangerous than alc.
Alcohol withdrawal is very similar to benzo withdrawal and can actually be more dangerous than benzo w/d. Again, it all depends on how much you've been drinking and for how many months/years. You can have seizures and die from brain damage from severe alcohol withdrawals, just the same as with severe benzo w/d's.
