i haven't ever done it, but i have done extensive research on it as far as producing it yourself, history of it in the US and europe, and what exactly it does.
absinthe is still legal in several european countries such as andorra, ibiza, spain, the uk, and the czech republic as well as a couple of asian countries. it was banned mostly because of people doing idiotic things while on it. it was really really popular among artists. it is believed that van gogh was under the influence of it when he cut off his ear. oscar wilde was also said to be a famous absinthe drinker.
basically what causes the effects of it is this herb called wormwood. in large quantities, it can be highly toxic. this is why people are advised against synthesis of absinthe as in concentration, it can induce death...especially if you use oil of wormwood as it is highly concentrated. you can have it shipped into the US, but i would advise against it as it is illegal.
as far as the effects of it, i have had friends who have drank it before while they were in europe, and they said it has an almost opiate like effect. i guess sort of like smoking opium, but definitely not to the extent of something crazy like heroin. has hallucinogenic properties when drank in a little bit of quantity. also it has an extremely high alcohol content. drinking anything with a lot of wormwood on it can cause renal failure, so beware of that.
it also is said to taste like licorice since it has a lot of anise in it. it is chartreuse in color. a legal version of absinthe with a lowered alcohol content ixnay the wormwood is Pernod. it is drank with a sugar cube and accompanied by an absinthe spoon. there is a lot of history with absinthe also that circulates around new orleans. it's highly involved with gothic culture too. very interesting stuff.
some people try and make it themselves by steeping wormwood in vodka or pernod, which is horrid tasting according to many sources. it has to be distilled in order for it to be fully effective, anyway. like i said, i don't recommend making it. the best thing to do if you want to try it is go to a country where it is legal cuz you don't want to die due to someone being stupid and distilling it improperly.
an online FAQ is available if you want to read up some more on it:

hope that helps you some. sorry i can't give you a personal account of it's effects, but i figured i would at least give you some background info on it.
