Im new here and also new to Lyme disease, which is a nasty beggar if you havent had it, and just wanted to see if anyone can relate. I take Doxycycline x 2 100mg tablets and it is the worst feeling ever. I also have Raynauds as well as CFS and I find that this medicine intensifies everything, especially if Im "Herxing". Anyway, thats a little about me. I have constant brain fog, tinnitus in both ears, depersonalization/derealization on top of all of these other symptoms and its a bit overwhelming. Can anyone relate to this?
