Adderall Toxitiy: I've been taking 90 mg tabs for approx. 4 years. Never a problem until the last 6 mos or so. Bottom lip dry, shiny and numb. Dry burning eyes. Burning tongue, cracks in the corners of mouth. Salivary glands not functioning properly. I'm sure it's the adderall, but don't want to dis continue . Can my side affects be medicated
