I've seen lots of those types of questions here on SR. I take it people use them for craving suppression ? I also recently noticed a similar sounding chemical/medication being advertised for cravings related to food.
Many adopt the idea that abstinence in the presence of cravings is not only possible but really the endgame.
It is my experience that cravings diminish and become less frequent the more times they are 'rided out'. It seems just as habitual as it is to satisfy an urge or craving, when that urge becomes habitually ignored it loses it 'potency'.
It makes me wonder how helpful that can be, if medication suppresses the urge and one is not then able to practice the habit of having the experience of riding them out. Or are these types of medications only prescribed on a short term basis ?
