it probably is what is making you sedated and yes you will adjust. You should talk to your doc or pharmacist, but i would imagine that it should be ok to hold off on increasing the dose until you do adjust. You should also ask your doc as to whether the increase is even necessary... i mean once you adjust to the sedation, if you feel better then why would you need more?
i did prefer ativan as i find that klono stops doing much for me after a while... but there is some other reason why my pdoc stuck me with it.. can't remember why..
