Minocycline dangers

I did read that Minocycline can thicken the blood or arteries.. so I will only take it for 7-10 days. So far Im feeling that the laetrile b17, reishi powder, noni and minocycline are working in a different way than past remedies. Not sure if thats a good or bad thing yet but I do feel ok. After 2wks off antibiotics i had no short term memory and i noticed the problem yesterday as well. Been taking the mino for 7 days now. I am also feeling the symptoms of the fore mentioned thickening where i get brief head pains. Have not tried the shark cartilage yet but im thinking about it. I feel so close to being rid of all of these symptoms but just cant seem to shake it all the way off just yet.
