How much does this cost $ ? I am an adult male an am in therapy for AADD and Mild depression. I am on Methylphenidate ER 30mg 2x daily, and methylphenidate 20mg 1x daily and would like to try Wellbutron as an adjunct to hopefully reduce the sexual side-effects of the Methylphenidate. Also is the chemical makeup of these two drugs different, hope you can help. also i am living below the poverty level.
