If you're very skeptical about medication then that's the best way to take it imo. I was really skeptical about it and never wanted to rely on it. Now I'm on it I only take it when I need it, which is just at work mostly. Any holiday I take I'm off it, any day I don't feel I need it at work I don't take it.

So I never need to increase the dose really, it's really manageable and just a good perk to have. Respect not taking it, but the worst thing I believe you can do is take it constantly and slowly get to the highest dose and can't live without it.
