A lot of people have tried medications, but the side effects have discouraged them from continually taking them. For others, they have "bad days" and "good days", perhaps their condition is not that severe that they probably can still function without medications. In these two cases, the only alternative "treatment" to improve their mental health is to improve their overall physical health.
When a person is already aware of the fact that they have a mental
health condition, it's important to avoid drinking, smoking and taking
any substances that would alter the chemical makeups in their brain. For
me, I can't and I don't even drink regular coffee. It would make the
quality of my sleep poorer and shallower. Often times, when a person is
depressed, they tend to abuse alcohol or other substances as a coping
mechanism. Unfortunately, it would only worsen their condition.
It's so trite to say, "we should drink 8 glasses of water each day, eat a lot of veggies and fruits, stop eating junk food, exercise regularly, have at least 6 to 8 hours of sleep each day, have a healthy lifestyle, etc. etc. " The truth is, they really are the keys to maintain and improve a person's mental health in a way that most people are not consciously aware of. The positive changes are slow and gradual, but once our physical body is clear of all the toxic substances and is well nourished, we will feel much better mentally. On the other hand, it takes extra amount of effect and energy for a depressed person to start making positive changes. It's easy to get pulled down but hard to bounce back. The effects are not immediate and it can be discouraging, but you gotta persist and not give up. It's worth the strive.
