I’m really sensitive to stimulants. Psych prescribed Wellbutrin and then Ritalin for my PCS. I was bouncing off the walls, unable to complete a thought let alone any work, then crashing horribly when the stuff finally wore off. I found I was better off self-dosing with tea and/or coffee as needed, which my GP told me is known as “bio-hacking.” So much cheaper—and tastier—than a shrink and Rx meds!
