Is it normal that my life is all drugs and sex?

For several years now my main activity has been to go to concerts, partys, festivals, or even just hang out at ppl's places and do drugs and just go wild. Something crazy always happenes to me, like every weekend basically. I feel like I know an unusual lot of people, it's becoming too much because sometimes people start to contact me during the week and I don't like to cling on to anyone and sometimes I forget who they were. I also have a lot of sex, it's my other hobby. But I'm also really into philosophy, psychology, physics and art, and I just love having discussions with strangers for nights about such things. It's giving me far more insight than my current academic development. Sometimes I'm at a point where I feel like my body can't take it anymore. And generally I'm a happy person, but oh the comedowns. All the way through the time of becoming an adult, I already did drugs and I don't know how people have grown up without acid, for example. I'm part of a world that is seperate from anything deemed acceptable, but I'm not willing to give in. I don't wanna have the same shitty boring life almost everyone else seems so have.
