Hi: I have been having vomitting issues since I was a child. About every three weeks, I have a sudden rise in temperature, excessive sweating and feeling like I am ice cold from the sweating, then I vomit and am unable to rise for several hours. Sometimes there is headache as well. I am 51, slim build, and I do not eat well (just have no interest in food). Recently diagnosed with bi-polar 2 disorder and anxiety. Medication (lithium, ciprolex) control the symptoms well. But as a therapist, this problem threatens my work (it's happened even in session!!) Doctor has been silent about it for my whole life (just literally shrugs his shoulders). Is this normal, common, and what can I do to stop it??
