Gretchen - well when i first started i took 200mg. which was the m.s. trial dosage but it made me very sick. i waited about
1 month and started at just 50 mg a day and yes i did have nasty headaches for a couple of wks nothing else. after 3wks u bunmped it up to 100mg per day and did fine no problems at all. once my body got use to it i couldnt even tell i was on it. i was taking it for a total of 2 mths give or take a bit and found out i was preg. sadly i had to stop the minocycline. a wk later i lost the baby so i started it back. ive been back on it for a wk and 1/2 and my headaches are starting to get better. my goal is to get use to the 50mg again then bump it to 100 then 150 then 200mg. so far it has been a blessing for me not to say it would work for all but me im happy and feeling much better. in a few months i will have another mri and then i should know how well its working on preventing any further m.s. damage. oh keep praying
