I am assuming you mean "Ativan". Taking normally prescribed amounts of both would not cause an overdose.
alcohol

By taking it.
50 mg

An overdose of both substances is possible. While a PCP overdose could certainly prove fatal, an overdose of LSD is very rarely fatal and would likely cause only an extremely unpleasant and overwhelming altered state with anxiety and panic.
about 20 pills of 50mg.
The drug known as "Alprax" contains a benzodiazepine called Alprazolam. An overdose of this alone would not usually cause a fatality but it can be lethal when mixed with alcohol or other drugs.
By taking more than was prescribed for you. This was no the question asked! Pay attention! DO YOU HAVE ADD?
