Input: My doctor prescribes me ritalin 20mg twice a day this works great for me but I need to focus for 12-13 hrs would a doctor do 20mg three times a day?

My doctor has prescribed me with MDD XR 50 (desvenlafaxine) a few months ago for an anxiety disorder and depression. Now I want to stop it. But once I skip it, the next day I am vomiting, have irritation and indigestion-like symptoms. What should I do?
