Something I see many people fall into is expecting the high to be something, or, to do something for them. This expectation will lead to resentment and feeling let down by the high (possibly much worse when you go seeking a "stronger" high) when the user really went in with no intention in mind. With no intention in mind you will end up doing nothing, much like having no intention in mind and going into a social network only to emerge 2 hours later not feeling satisfied.
Unlike several of the comments here I found that I was more social, more active, and more willing to take risks in all aspects of life than I would when I was sober. It has led to a sustained and growing yoga practice, which also led to something of a "spiritual" side I had never noticed. Projects I had dropped over the years have been picked up and completed without the fear or failure or ridicule that comes from an incredibly high anxiety while sober.
