... is dangerous since one is a stimulant and the other a depressent? I take 20 mg of adderall x 2 per day... I should be taking my adderall early but that is when my pain which we think is related to me possibly having lupus, is the worst so i wake up and take my oxycodone then wait until 2 pm or so to take adderall which in turn puts my other dose around 5 or 6 and I don't get to bed till 2 am! Please help!
