Perhaps 2 sprays isn’t your “sweet spot”. Also, you only tried it for one day so far, give it a chance. It took me awhile to “get it”, but once you do, you’ll be fine.
Stick with the IO for now, since you started with that. Use it regularly, in different doses, in different situations. You also need to be “congruent” with it, that is, you have to make some effort yourself - people aren’t necessarily just going to start talking to you, you need to position yourself in such a way to make it happen more easily, try starting a conversation with someone first, then watch it flow more easily than you might have expected.
Plus, as TwistedOstrich pointed out, if you are around people who are already used to your phero signature, it make take them a little while to adjust to the new one. I’ve found more instant results with people I’ve just met.
