Is it normal that i keep spitting/swearing/gargling unintentionally??

It happens all the time and it drives me nuts! Or maybe there's really something wrong with me ...

I've been like this since I was 5 and it started of with throat gargling; after that I keep having weird habits every few months like faking vomits or eye twitching; mouth twitching. On the occasions I keep spewing out swear words unintentionally (not that kind of swearing when you're angry, more like I felt a pressure forced me to say such things) ...

These tics are annoying and disgusting as hell, but I can't help it :( Am I normal??
