@ainsleigh @parus, I have a new psychiatrist and she intends to do a cheek swab on my next visit. The med she started me on just hoping to give me some relief from the twists and turns of my last two (nothing malicious, just a newbie and a very old one) may not be the right one for me as we discovered after taking it for a week, but it may just be a little early to know. She also said that it would help with titration of dosage because she will learn some things about my metabolic rate and not only with what she prescribes but also the pain medications I take. I will report back when I have some results, but I expect that to be a few weeks. Peace to you both, Gary
