I do it once in a blue moon. I'm not huge into it. The last time I did it, it burned my throat, so I must have done something wrong. I'm not too keen on doing that again.
I do it occasionally, it's very relaxing for me. Honestly, I get very light headed when I do but I sleep soooooo well. It's such a relaxant for me after work, but I don't do it often because my sister hates the smell.
