I notice a stark decline in mental ability when consuming high levels of caffeine. Drinking salted water helps - for awhile. Then it’s out the downward hatch. How much salt does one need to drink to prevent electrolyte imbalances when caffeinated? I only notice this when I consume more than the average amount of coffee.
Grief, anger, despair, sadness, frustration, hopelessness, bitterness. Why can one feel any of these emotions for days and then eventually feel better even if circumstances have not changed, or there has been no lack of progress mentally to address or process those negative feelings? Are there hormones connected to negative emotions like the "happy" hormones with positive emotions? (This is, of course, assuming that a person does not have depression etc).
