Experiences - LSD isn't as good as expected

[k-explorer]

SWIM used to eat magic mushrooms regularly when they were legal in the UK, especially some of the really strong types. Combined with what SWIM was learning at the time about different types of meditation, hypnosis and energy, SWIM had some really amazing, powerful, life-changing experiences.

When the mushrooms became illegal (and harder to get hold of), SWIM moved onto acid. Although that's also illegal, SWIM found it easier to get. SWIM is a big fan of Tim Leary's work and thought trying acid would be even more mind-blowing than the mushrooms, so SWIM was excited about this new step.

The first trip was okay. It wasn't as strong as the mushroom trips and it felt more chemically, but it had similar effects to the mushrooms and SWIM enjoyed it and learnt some cool stuff.

Each trip since then has been increasingly disappointing. SWIM has persisted a few times (with acid from two different sources) but he just isn't getting the amazing, spiritual experiences that other people describe. It's become really disappointing.

Here are some of the details of SWIM's last trip. On the plus side, SWIM had some really great feelings in his body for the first 2-3 hours and tapping any part of his leg (for example) created waves of pleasure that were hugely intense. Also, music sounded amazing for the first 2-3 hours - really amazing. However, on the downside, the trip lasted for about 30 hours in total and felt boring after the first 4 hours. SWIM couldn't get to sleep and was just bored listening to music or watching tv. SWIM's jaw was tight and he shivered a lot (though he wasn't cold) and felt a bit nausious. More though, it just wasn't magical like the mushrooms were. There were no visuals, no big ideas and no spiritual dimension. It was pretty boring.

One thing that might explain this is that SWIM took two blotting papers the first time and has taken 5 each time since. Maybe 5 is too much? SWIM assumed that taking more would get more of the good stuff, but maybe less is more with acid?

Or maybe SWIM is getting used to tripping and needs more than 5 now?

Alternative idea: maybe SWIM is not getting real LSD? Could something else be posing as acid and causing the trip I described rather than a real acid trip?

What do you think? Any suggestions?
