This is not the place to be asking these kinds of things, small one. The Clinic is for team advice only. Locking and moving this. Be sure to check the forum descriptions before making a topic to make sure that you're posting it in the right place. Also make sure to the rules if you haven't already.
And no, PokeRus is not a bad thing. It doubles your EVs gained from battling Pokemon (not vitamins) until it wears off.
