Will I p my drug test tomorrow afternoon?

Hi, this past weekend I used DXM and heroin Friday-Sunday. My drug test is tomorrow (Wednesday). I've been exercising a lot, going for long bike rides and jogs. I've been layering up in clothing wearing like two sweat shirts and two pairs of pants going for moderate long jogs around my neighborhood occasionally making sure I sweat a lot. Today, I took three 250 mg Niacin capsules and downed them with a Monster Energy drink, then proceeded to exercise for the rest of the day. With all of that said, are the precautions I've taken enough for me to p my drug test tomorrow? Any feed back would be greatly appreciated. If I fail this test I get sent away to a camp for three months.
