The only time during all my years of lyme and treatment protocols that I herxed was when I begged my family doctor for a prescript
ion for Doxy and he gave me enough for 1 week.
I herxed for 2 or 3 days and I was taking 100 mg twice a day. I was sweating, felt really hot, then got chills, felt really strange and when it was all over I felt great. But that 1 week prescription was not enough and because I didn't have a positive blood test at that time he refused to prescribe more Doxy for me. When I finally did see a LLMD I was given Doxy but never herxed but it.
From what I have learned all these years, a hot body is good compared to a cold body because lyme spirochetes can not survive in a hot body but love a cold body.
And RD, yes, one must avoid the sun when taking Doxy as well as eating some food with it. I didn't know that at the time and my head was in the toilet bowl too many times after taking Doxy on an empty stomach, not good!!
Oh, before I forget (I am getting older), never lay down right away after taking Doxy as it can do damage to one's esophagus (ulcers I believe).
Hope you feel better Veromia,
