Bupropion
"I'm 60, male, have been on bupropion xl 150 for 2 months. A little anxious the first few days but feel great now. Took away the lowest dark moods i've had for decades. Some decrease in libido but manageable. Contrary to reports i've read, has brought back my ability to remember things and focus much better. Has quietened the negative internal dialogue i've heard for years. I work out hard, have a very physical job, and if anything it's given me more energy. I do notice I sweat more, and though I work a graveyard shift, hasn't hurt my sleeping. More vivid dreams, but I like the show. Almost a vegetarian (only meat is fish),  eating habits unchanged. Don't plan to take this long term, but so far, so good."
