I used it in the past to help my depression. It worked well for a while and was very fast acting, but the latter also meant the effect did not last long (a few hours) so I had to take it multiple times a day. It took a bit of experimenting to find the right dosage and timing to take it for me and this is also what I read from many others. Taking too much made me feel weird and gave me gastrointestinal side effects, taking too little no positive effect. For example, I had to take the largest dose in the morning and very little or nothing in the evening otherwise I would not be able to sleep (interesting, because many people take it as a sleep aid). I thought it was a life saver for me during the worst of that depressive episode as I was not taking prescription meds or receiving any other form of treatment. I found it stopped working after a while, although perhaps I was just not that depressed anymore so did not feel such a difference.

In case you are taking other medications, I would definitely discuss with your doctor as it can have interactions with other drugs.
