My experiences with these drugs:
Wellbutrin: energy, focus, motivation, anxiety, insomnia, constipation, irritability. Felt like a driven and ultra productive robot for awhile. The Uber focus and motivation went away after a couple months, leaving mostly undesirable side effects as the remaining effects. Under the influence of wellbutrin and alcohol, I was involved in a road rage incident where I almost killed a motorcyclist.
Selegiline: initial energy, mood boost, and dopaminergic good effects that give way to irritability and fatigue with continued use. There may be some mild lingering benefit that did not outweigh the side effects for me.
