Weired Feelings

I have been visiting this club for the last month or so, I know most of the girls there are probably on drugs or something, but the last time I was there I did a private dance with one of the dancer who did french kissed me a lot before doing any thing else, any how it was enjoyable and gave her a good tip, but as soon as I left the club I felt like I am on drugs even though I only had 2 beers, and the next day I had strange feeling too with a headache, I do not know if I also became addict it to what she had or not because the shit they are taking these day is very strong, but no more kisses in the VIP. Any body else had this kind of experience? help please
