If you need to take something just to get through, you really should be asking yourself if you should be attending at all.
Most of the prescription drugs discussed here are not intended for long-term or regular use, (for example while you might pop a Xanax to get through attending a JW funeral, it does not mean you take one before every meeting). Most of these things are addictive.
As for ADs, unless you really have a chemical imbalance, these too will do more harm than good over the long-term. So many JWs take these things precisely because they are in a depressing environment much of the time. I was on them for 4 years before I left. While taking them, I noticed if affected my normal ambitious drive at work in a negative way, (I was far less ambitious). Once I quit going to meetings, I did not need them anymore. 10 years later I still don't.
