Medical professionals probably do say good things about it. But lets look at this closer: They probably say good things about medications too - because most people react well to it. This doesn't mean that it doesn't cause problems in a few people, nor that you will hear about it.

For me, it makes it so I'm angry. I'm unhappy with everyday life. I'm frustrated all the time and I dread the sessions. I've found some meditation styles that don't pick up the mindfulness and kept them up for a few months: but basically, I was sitting there being bored once a day and didn't have anything to show at the end for the work I had done. So I quit. I would certainly never do a retreat because I think I could be that person.

LSD (when I was younger) and other hallucinogens (now that I can vacation in Amsterdam) have, however, helped a great deal. More than meditation. You see, it seems to me that for meditation to work, you have to know how to produce some of these feelings - or at least recognize them in real time. You have to understand how to do what the stuff says. You have to be able to not beat yourself up for failing (which is difficult if you have perfectionist tendencies or some fear of failure). The other is more ... forced positive feelings, plus some altered thinking. Suddenly I remember what this is all like, and can take it to my daily life.
