I stopped Pravistatin fourteen (14) months ago and although almost all the very severe pain has left me, I know that it is still in my body. It seems obvious to me that statins travel to all parts of the body and can reside in the brain as well. Their effect can be mental and emotional as well. Memory loss, short and long term, plus emotional swings are another disturbing side effects. I get the flu symptoms after sex, still after over a year. For some men it will cause erectile dysfunction along with low libido. Lack of focus is another I was a long term user, more than two years, and it may never leave my body entirely. I am waiting for the two year anniversary in hopes that it will finally exit my body and brain.
