I've dropped about 7 times.
When I first did at TAO i fell in love with the drug and did it the next two weekends. Very quickly did I notice that it is impossible for most people to reasonably do E weekly. Now I keep it to once every 5-8 weeks and I believe I'm going to slow down even more to a minimum 2 month steady pace.
I still love E and really think the massives vs. dropping at home with friends are two separate and uniquely amazing experiences. Once you drop with certain people you share something with them that you don't have with others.
