I am currently getting high every other day on Sudafed, Adderal and Lexapro. I have built up such a tolerance for this that sometimes I take a box and one half of sudafed 12hr. (120mgs) That is 30 pills, plus the adderal XR(30mg) and Lexapro (20mgs). Last night I felt nothing. I want to clean myself up...how long will this stuff take to get out of my system???
