I had a dip at one time. Solutions attempted (linearly in path):<p>- Adderall: task execution increased, but general success did not<p>- Caffeine: same as above<p>- Spend more time with all friends, weighted higher for closest: Positive pleasant experience. Work performance did not improve<p>- Better Sleep Timing: Mood improved, but general success did not<p>- Sleep Tracking: Watch revealed low pulse ox. Sleep Apnea tracking device did not. However, deviated septum and enlarged turbinates. Intervention (anti-allergy meds period of use not over and surgery I did not follow up on)/<p>- Exercising regularly: Got addicted to this (1x Barry's a day for 60 days, my weight lifting numbers at end - I already knew how - 375 lb DL, 275 lb back squat, 225 lb front squat, 175 lb bench [lame], 135 lb C&J, 105 lb snatch). Work outcome dropped - I'd rather hit the next PR than submit a PR, if you will<p>- Diet modification: Attempted zero-sugar, attempted high-greens+high-meat, attempted ice-cream-only (no significant change except lost weight), attempted take-out-only (gained time, but wasted the gained time)<p>- Switched job: Quitting had the best outcome on mental health. Performance did not spike at new job.<p>- Switched out of remote to in-office: Massive improvement in mental health and performance.<p>I can't guess at what your experience is, but this is a summary of my raw experience. For background info, I am in my 30s, live in San Francisco, and I am fortunate to have lots of friends across backgrounds and genders to whom I am as important as they are to me - this part was important since it provided a base level of self-esteem through their support. Completely normative otherwise.
