Well Ithink I took it twice because I was in a hurry running late and tired. It hasn't kicked in yet I dnt know if I took one or two. I have anxiety but also add and I'm prescribed concerta and paxil. I think I took one concerta then I had to pee really bad before I took my Paxil. But when I came back I forgot and took concerta instead of Paxil. I think but not sure. If I took 2 36mg if concerta am I ok? I'm 21 weigh about 170. Female. Five foot three.
