Well Roxicodone only comes generic now (at least where i live). 30 used to do it for me railed. The first couple times i just sat there feeling amazing. 60 used to make me sick. Well now 30 doesn't work, even though i don't do them on a regular basis (1nce a month?) It just doesnt seem like 30 even feels the same. So if I up the dose can i get the same feeling as when i first did it? And since I'm not tolerant will i get sick still?

You dont have to do them every day to gain a tolerance to them. Your going to have to bump up to 45 mgs now. I promise you it is not because it is a generic. The only thing about generics that could differ is absorbtion MAYBE but a 30mg generic has 30mgs in it just like the label says.
