so I was recently prescribed butrans patch 10mcg but I had gotten really sick as it was too much medication. Dr told me to cut it in half and try again 20hrs later. I waited 1 & 1/2 day before I put ,What is now , a 5mcg patch on. Today is the third day and I am still not having pain releif. Instead I am ridiculously drowsy and blurry vision . Anyone have this problem? Should I give it more time ?
