Hi I am new to this forum. I was diagnosed with chronic/later stage/CNS lyme disease in November 2014 (after years of knowing something was wrong). I know that I was infected in May 2008 after spending time in the Smokey Mountains, I am guessing that I may have been infected as a child also -I had a number of growing pains that were not explained, allergies, sleep problems, and cuts easily became infected. I was treated with oral ABx for a few months and started IV antibiotics on 5/4/2015. I am taking 100 mg 2x day of Doxycycline (via IV) and Tinadazole 250 mg 2x day orally. I read on one of the forums that Doxycycline should be taken at a higher dose and am wondering if this applies to IV, or just oral administration. I'm trying to do a number of cleansing routines (including epsom salt baths, Infrared sauna, lemon water with olive oil, healthy diet, and a number of supplements), having a hard time staying steady with them. I haven't noticed a change in symptoms yet and have noticed increased fatigue and irritability since going on IV antibiotics.

I have read it's 400 mg daily for IV doxy.

I've been asking myself the same thing... When I was on IV Doxy, I was given the same dosage,200mg/day over 30 mins... 200mg was already pretty heavy: towards the end of those 30mins, I would almost fall asleep while sitting up.
