I wonder if taking oxytocin supplements might work even better for this.
I'll definitely be trying it in one way or another, though.
Alas, oxytocin supplements (there is a nasal spray, if I remember correctly) don't seem to work. When released naturally, it's released where it matters and in precise amounts, while the shotgun approach of the nasal spray makes it easy to miss the correct dosage and delivery location, which may cause various adverse effects.
Warning: my source on the above is a popular book, Cupid's Poisoned Arrow -- but, to their credit, they do cite their scientific sources. If Kindle had a way of copying / quoting text from its books, I'd look up the relevant paragraph ...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
