Right, it's important to note that side effects are not always things that show up immediately; some may never show up until withdrawal, so do the research before trying new drugs. Drugs that affect neurotransmitters are much more likely to cause important withdrawal problems than any other drugs, though certainly other drugs (that regulate heart rate, blood pressure, etc) can cause withdrawal problems as well. Doctors are notoriously unwilling to mention all the side effects without being asked (and sometimes despite being asked), for any kind of drug, so it's kind of up to the patient...
