Thank you so much for your responses. I am taking Drenamin, and I haven't had an "episode" in about a month. Unfortunately, I am so ill that I can't get out of bed. My doctor diagnosed me as having severe hyperemesis gravidarum, but I know it is more than that.
The reason my midwife though it was adrenal was that my symptoms were so severe. With both episodes, I woke up with shaking, convulsing, shivering, vomiting, chest pain, unable to swallow food, unable to get to the bathroom without help. After these episodes, I would crash with extreme exhaustion. I began having frequent strong dizzy spells, early waking (like 3am-5am, for no reason), and crazy "fight or flight" responses - like I'd hear any noise and feel like I was having a full blown anxiety attack. At one point, I was having head-to-toe anxiety every three minutes.
I noticed improvement after a week of taking Drenamin, Vit C supplements, and omega 3's. I'm not able to change much, diet-wise, because I still have a hard time eating with the bad nausea.
I didn't think 2.57 TSH was abnormal, but the dr said it was "on the high side" for pregnancy, and with all of my symptoms he wants me to consider medication, but I think I will go ahead with the rest of testing first, including for Hashimoto's (sp?) Disease.
I appreciate the advice a ton! I am a little concerned that the Drenamin will be disguising the problem and my tests will come back normal, even though there is something wrong. But I don't see how I would have gotten by without it.
