I find that low doses of SJW helps me sleep. I was prone to depression all my life until I went onto Hormome replacement therapy (HRT), years ago, and earlier than most women. That has stabilized me emotionally to an amazing degree. Now I only lose my equilibrium in response to clear stresses in real life -- which has been a really astonishing change in my life, and has demonstrated to me beyond any doubt how much depression can be simply physiological. So I only take SJW when I'm having trouble sleeping because of real life worries. It may be that I am very suggestible, but I generally find that it helps almost immediately, not after weeks of building up in the system. From my years of experience before HRT I have enormous respect, bordering on awe, for how real and serious and intense depression can be, and how debilitating, and how useless, even damaging, it can be to say things like "You need a hobby!" or "Why don't you take up tennis", or any other well-meaning but completely irrelevant suggestions.
