Hi Heather,
I was on zithro for months, and it was horrible. I herxed non-stop, my heart would sometimes go crazy. From all the abx I took, this one is the worst, together with minocycline. If my dr would tell me to go on it again, I would refuse - lol.
Please take it slow, do everything you can to detox, and give your body time to recuperate, over and over again. Do slowly with the GSE too, it can be too much at a time, could release too much toxins. Step by step. If you weren't able to leave your bed, getting up is already an achievement. Getting some things done may be too much of it.
You'll need to set some bounderies to yourself, and accept it, it's hard, but once you found a balance, you'll feel more at ease. But it takes a while...
Please talk to your dr and discuss a possible change of protocol. The disease is so hard on one's system, treatment puts a huge strain on it.
