The use of this medication is rampent in college. It personally disgusts me, as all drugs do. That aside, all chemicals that alter you mentally carry addiction factors, even if there isn't a chemical reason for addiction there are mental one(liking the feel).
The side effects can be pretty harsh and the factis itsmost likely forcing the release of chemicals in your brain whichmeans that continued use will eventual build a tolerance both to the meds them self as well as the chemical reaction the cause in your brain which will lead to higher dosages to achieve the same effect.
You're basically abusing perscription drugs, which is pretty prevalent in society and a leading cause of death now I believe. Regardless its illegal and could be bad not just for you but the people you get it from.
Also based on your description you're as likely to do nothing as you are to do something on these drugs plus you stilldo seem to be under the effects so you have no idea what the detox or crash is like yet.

I would advise against continue use but you make your own choice.
