A virus can take 3 months to fully clear out of your body. Be patient and let it take it's course.
I swear by ginger tea. You can either grate it, or buy it in teabag form at most stores. Just sip it straight, without sweeteners. It helps me tremendously, as my anxiety is characterized primarily by dizziness and nausea (without vomiting). I keep packets at my desk at work for those most trying moments.
Oh, and someone started a very valuable thread about hormones and anxiety, which I truly believe go hand-in-hand for women. Perhaps you could discuss the possibility of a hormonal imbalance with your doctor. I'm about to do this myself. And you have my sympathy...I didn't keep up my fluid intake when I was recovering from bronchitis, and I passed out at the pharmacy due to dehydration.
I too am feeling these same symptoms. I noticed the attacks after going off birth control almost 5 months ago. I was having mild panic/anxiety attacks and decided to try the drug Lexapro which was a big mistake. I ended up having an allergic reaction to it and landed in the ER. I even missed 3 days of work and all from 1 little pill. I asked the doc if it could be hormonal and he said yes and put me back on my birth control to see if that helped with the panic/anxiety attacks. Since then (the past month) I have felt extreme nausea. I have lost 10 lbs and can't keep food down. My appetite is completely gone and I have no energy. I am starting to get very concerned as it has consumed my life. I wanted to loose weight, but certainly not this way. I have a follow-up visit with my doc tomorrow. I am going to ask that he test my blood, hormones and thyroid. I have already taken 2 pregnancy tests which came back neg. I have had one pregnancy and never experienced morning sickness, but I imagine that this is what if feels like.
