I am on a 24 hour patch for 12 days now and during the second week I had a headache which lasted for 3 days. I took the patch off before bed to see if it improved which it did however I didnt replace it the following day. I attempted to go to work but had feelings similar to being high, confusion, foggy head, totally not myself. I had to come home, I put on a patch and slept. I feel better but still slightly hazy. What caused this?
