What dose are you currently on? Apparently the smaller doses are most activating and can increase anxiety and mania symptoms until a dose of 200mg or more is achieved that is more helpful towards stabilizing the ups.

This is all "apparently"s, just stuff I have encountered people saying in the past but no Pdoc told me this. I also do not have experience with this as I do not have mania, but I did notice at around 50mg I was getting weird anxiety tummy feelings and freaking out whenever someone was late to something (thought something bad happened.)
