There are some prescription meds that are important long term, but you can do without for a while. I am taking a drug for cholesterol, but nothing is going to happen if I don't take it every day. I also take a drug for high blood pressure. That is a symptomless disease. Taking it daily is a good idea, but it's absence is probably not going to incapacitate me like failing to have Effexor available.
I know, somebody is going to say "you could have a stroke". True, that is a possibility as opposed to certain problems with antidepressant withdrawl.
