Magnesium....magnesium....magnesium!! and in case i forgot to mention it.....MAGNESIUM!!
sorry to hear you are feeling so anxious/nauseous, tobra and merrem used to do exactly the same to me, until i started taking a good magnesium supplement twice a day every day. Now i get through IV's and even oral Cipro no worries at all. In the past Tobra and Cipro expecially, made me so anxious i had to stop taking them.
The thing is, some of the AB's they put us on (Tobra and Cipro are two of them), seriously leech magnesium from our systems and magnesium deficiency mimics the symptoms of anxiety. With me, I presented with, SOB, nausea, appetite loss, racing heart, palpitations, dizziness. My symptoms were so bad they put me in hospital the last time i took Cipro before i started magnesium. I had never suffered from 'anxiety' in my life, until the very first time they starting me on a Tobra IV!! From then on until i built up the magnesium deposits in my system, i suffered from anxiety, made worse every time i took Cipro or Tobra.
Even though if you start taking mag now, you probably won't feel the effects for a few weeks, if you can get through this course of AB's, you should feel a lot better the next time you need to take them.
