What I want to say is... if something makes you feel better with reasonable outcomes, then it's a good thing. If it doesn't, than it plain doesn't and no use telling the person they should feel better with XY substance in them (going back to the whole fat thing. If the person feels bad because of the effect, they feel bad. It's not helping, end of the story).

But chasing the good feelings shouldn't end up realing on outside help. Unless you have reason to feel satisfied... than nothing is gonna work long term.
