It's all about coming off slowly, gradually lowering dosage and frequency and then once it is really low/you take it infrequently, you'll usualy end up just generally not bothering to take it and just stop.

Going cold turkey and suddenly stopping is a shock to the symstem and your body starts to suffer withdrawal symptoms from being so used to having the drug in you, doing its stuff.

worked for me, works for loads of people,
good luck
