Dom, no one is labelling you as bad, just that what you take may not be as good as you hoped.
Medications made in the mainstream carry side effects, even if it's just a possibility of a mild headache or slight drowsiness, a side is a side regardless.
These days the consumer has more choices, no matter what some sections of the media, medical industry and politcal circles try to do.
Evidence and results etc etc, will leak out, via dedicated individuals, personal testimonies, and those people in the three above catagories, that don't play charades with the individual on matters of health.
There are other ways if you want to find them, and other things out there for you to consider.
Mainstream and the alternative have no consistent record. Alternative is now well publicised enough, to know it's practicioners and exponents cannot shine like Gods of creation, and expect everyone to leave Mainstream in the dust, as the human body has been altered that much, by new and everyday things over cenruries, it's micro-evolution, remains a constant challenge to all, be it mainstream or alt.
No one is ever going to call you bad for thinking well of mainstream, as mainstream has success, but ultimately anything in life has success even with downsides. A vast majority of new things in science and technology, deemed highly positive, come with at least one con, for all the pros, because that's life.
You can believe in what you want with medicine, like I choose to be atheist in religious terms, but it doesn't make you a bad person my man, it really doesn't, but in this ever changing world, you sometimes have to realise, that it doesn't necessarily have to be the case, that you sit back, and narrow the scope of vision, hoping for vindication of your actions when you're old.
You can still believe in your mainstream principles even if you choose to look at other ways of doing things. It's not about who's right or wrong on here, or if you're right or wrong about anything, it's about you choosing the path you feel best suited to you, and knowing it's not the definitive route in life, and you can walk a different path, but ultimately, you'll still be walking in the same hypothetical shoes, from cradle to grave, and if you are having to take several meds in your life at your age, then to increase your understanding of what is possible for you, can only serve to benefit, even if you choose to stick to what you feel is best.
Don't take anything others here say the wrong way, but if some people didn't express concerns for a young man with your situation, and physical issues, they wouldn't feel too good, knowing they could say something and didn't.
You can choose to take on board what's said or not, and choose to diversify what you know, even if you end up always believing in what you are doing now, but don't mistake care and concern for personality bashing of any kind, it's not the case, and I've been here long enough now to say, I can vouch for every single member of this board, in regards to their honesty, human gifts, and quality of Heart and personality, and I hope you'll see it too.
We want what's best for you fella, but we'll NEVER force you to think or believe anything you don't want to. You're old enough to sensibly and rationally make those choices now, but we'll never stop as a community, looking out for one of our own okay
