Hi Pussycat! I'm also sorry about your health problems. I too have bipolar disorder, and I'm wondering why you must quit cold turkey? Does nicotine replacement therapy interfere with the blood thinners? I'm not saying that it's impossible for people with bipolar disorder to quit cold turkey. I've read, and my experience has been, that cold turkey quits have a tendency to bring on manic episodes. So the psych medications may have to be adjusted during a cold turkey quit.
