Urgent: Codein, Zoloft, And Antihistimines

Hi. I just had my wisdom teeth out today, and the doctor wants me to take 3 teaspoons of codein every four hourse. He never mentioned any problems with taking my other meds.

I got home and read the instructions. It said that there could be reactions with other meds that cause drousyness. I take two different antihistimines, one for ashma/allergies, and one for vertigo. I also take zoloft. I haven't taken any of them since this morning, but I don't want to have to not take them for the next few days. My ashma and vertigo will be really bad if I don't take them. It is also never good to go off of an antidepressent, especially when you area already feeling pretty bad just from the pain.

The problem is, I tend to react strongly to meds. The codein already makes me really tired. More tired than I would have thought. I'm worried that taking the other meds with the codein. However, I can't not take the codein because i'm in a whole lot of pain. He had a hard time getting one of them out, and the area is pretty bruised. I'm still bleeding 24 hours later.

What should I do? Is it safe to take my meds? My ashma is already acting up, and i'd really like to be able to take an antihistimine. Also, how do I tell if I am having other side effects from codein.

It says that slowed or shallow breathing is a side effect. That has always been a phobia of mine, so I don't know how to tell if i'm actually having it or not, especially when my ashma is acting up.

I really need to know soon. Can anyone help?
