We're up to one tab, and not going any further. No heroes here

No it didn't make us tired at all. For me it was like when your hands go numb (like pins and needles), except for the whole body, kidding was strangest. The sex was really interesting to begin with, then even my cock went numb but I could still feel the sensations in my prostate. Wife had two or three orgasms, I didn't try to finish.

Good question. We stick to a single dose each (rarely less), and we do go into different mental settings while having sex, maybe that's an altered dimension? For example, we listen to some Spanish style guitar music while tripping and having sex, and in our minds we are both in a saloon and I am seducing her and then taking her up to one rooms upstairs of the saloon. Another example is listening to some instrumental music that seems to have a rainy backdrop, so we imagine being in the 1500-1600s or whatever and it's cold and rainy outside and we are having some passionate sex. I typically drive the setting with dirty talk and my wife gets absorbed into my fantasy in her own mind.

As far as visuals go, nature and colors are much more vibrant and inviting, clouds are incredible. Strangely enough, on our last we would see a single bird flying, but it would somehow appear as three.

We've never had a bad trip, but we do a mind check on each other to make sure nothing is bothering us and we are in a good state of mind. I think if either one of us has a doubt, we would cancel in postpone till later.
