I wouldnt have them in my way but from what i ahve seen (and i havent seen it all) is that they cause as many probs as they cure.The have side effects ranging from bloat and weight gain to laziness and inability to focus.
I much prefer to be strong,fit and miserable than fat and happy.It really depends on the individual and side effects.
Understanding being off form is just part and parcel of being a human being would go along way in preventing having to resort to them.
