> feeling/impulses are artificially suppressed.

A lot of people are less capable of controlling those impulse on their own and are inherently more prone to developing addictions than others due to genetic/etc. reasons. Yes they can make different choices, change their lifestyles, adopt certain routines etc. all which would require a huge amount of effort just to get on part with people who can achieve those things (relatively) almost effortlessly.

Why should they be forced to suffer due to something they have limited control over?
