Should I consume drugs or alcohol before my deposition?

No. Do not consume drugs or alcohol before your deposition. At the beginning of the deposition, the opposing attorney is going to ask you a series of what I like to think of as introductory questions. One of those will be, have you consumed drugs or alcohol or any substance that may affect your ability to remember or recall events. It will hurt your testimony and your credibility if you are on some sort of mind-altering substance.
