Yes, I take it under the name Serotone which I buy from Higher Nature, excellent online supplier, very sound products. You can also buy from Holland and Barrett.
I find it easy to take. It gently lifts my spirits, helps me sleep, has no side effects and no no addictive qualities. But as with all these things, different people react differently so to be tried cautiously.
I expect someone will post a link with terrifying warnings. I'll just counter by saying my GP gaily recommended St John's Wort which I found horrible to take. We all metabolise things differently.
