The side effects are only an issue IF they affect you. If they don't then why stress yourself out over the POSSIBLE nasty effects they can have if the end result is an improvement in your condition?
I mean, if we all worried about how different medications would screw your head, liver, kidneys, heart, etc, then we wouldn't be here because either the ailment would have taken us out or we would have taken ourselves out because of the ailment.
And that means that unless you DEFINITELY feel thos side effects then you're stressing yourself for no reason whatsoever.
