Sharing your own experience is fine without suggesting that others stop taking medication.
Every person is so different and reacts to medication differently. It is impossible to give any advice based on our own experience.
I had a horrible experience with Welbutrin and just saw a client of mine have a horrible experience with Welbutrin. I know it helps many people here though. I would never make a blanket statement that others should never take Welbutrin. I might suggest they have someone monitor them if they are taking it for the first time.
We have to be careful here because we don't want someone to pass through and decide to stop taking their medication after reading a post here. It can be very serious for some.
