If you decide to stop it, you will need to taper to avoid withdrawal symptoms. Your body will get used to functioning with the drug, and if you suddenly take it away, you will experience some form of discontinuation--although the severity differs by person.
Ideally, you'd want to go in smaller increments, but you'd at least want to go from 50mg to 25mg for a few weeks--maybe go from a whole pill to 75% of a pill, then 50% of pill and then 25%. It involves cutting the pill, but it is better safe than potentially suffering withdrawal.

This isn't meant to scare you away, but it is better to go in with full knowledge than to encounter contradicting evidence later. If the ad was prescribed by a gp, they do not have the knowledge of a psychiatrist when it comes to slowly going up or down. Although honestly, many pdocs don't know or care to share this info with you either.
