When your pdoc achieves the lowest therapeutic level for you, there should not be any bluntness.
Before Lamictal I had been tried on 2 other mood stabilizers, which were blunting, sometimes it's just a matter of which mood stabilizer is being used.
It is not just mood stabilizers that can cause the blunting, many AD's (especially the SSRI's) can cause blunting. Before I was ever prescribed any mood stabilizers, I was being treated for clinical depression (mis-diagnosed,like many are)I had been on almost every SSRI known, very little help if at all, for my depression.
I hate to sound like I'm some sort of salesperson for Lamictal (I'm not at all) but wish to share with others how good it is . . . well for me it has been.
My DX given to me 6yrs ago, was Bipolar-II(mild)and
ADD (mild) the Bipolar, having mild to very slight hypomania, Lamictal works well for staving off bipolar depression, and is not blunting.
The right med. and dosage will not take your creativity, in fact I've heard,read and experienced, if anything stabilization can be of help in the area of creativity, and organizational skills.
I guess it is all individual,I still want to urge people not to drop or deny themselves of mood stabilization/treatment, instead talk with your pdoc about options, any alternatives.
It's not a good idea to play pdoc with yourself,may even set back progress.
Just my opinion, which I have arrived at from real life experience,psychiatric journals/articles,observation of others with Bipolar and conversation with some psychologists, and several pdocs.
What has worked for me may not for another person and vice versa, it's a matter of keeping an open mind, and giving things a try.
I wish you luck and hope discussing this issue with your pdoc will be fruitfull.
