I am very sick at my stomach, muscles ache, headache, and very sleepy..... I am wondering if I have messed up by taking a couple of methodone pills when I already take Zoloft. I didn t read up on it BEFORE I took it, but as soon as I started feeling bad, I did and it says it s contraindicated with Zoloft. I haven t taken either one since night before last. Would I still be feeling this way as a result of that?
