I was diagnosed with CFS early this year then Lyme/Babesia in Sept. I've been taking Zithromax for about a month and a half and I started Flagyl about 2 weeks ago. My symptoms have gotten much worse once I started the Flagyl and it is really scary. My stomach is constantly upset, and I am not throwing up but I feel like I always have to, my appetite has gotten much worse, my fatique and lightheadedness, light/sound sensitivities are much worse as well. I've already lost like 20 pounds since March when I relapsed and I can tell that I have lost more weight in the past 2 weeks which is really starting to scare me because I cant hold anything down and I pretty much have no appetite. I just feel like I am slowly dying and dont know what to do. I dont know if I am worsening because of a herx from the antibiotics or if they are just further damaging my immune system. I really dont know what to do.
