When I was younger, tried them and got a headache. A couple of years ago, I tried them again while playing with toys and got the most incredible rush and pleasure. I think I've overused them as they don't seem to have the same effect even if I am off them for a week. One note: I used to buy online, but now a lot of the sellers don't take credit cards. So, a hire of mine referred me to

So I placed an order. Supposedly shipped, customs and in the delivery network to me within a week. It is now over a month and I have yet to receive them. When I inquired I got a snippy response that it could be customs or the post office. But even if it is one of those two, that is what you would have to deal with when shopping with them. Out $55. I would advise NOT to use them.
