I guess I’m the odd man out.
I use caffeine pills and don’t drink coffee. I need the lift an hour or two after lunch. I cut a 200 mg pill into quarters and “microdose” 50 mg, then wait a half hour or more to see if I need another 50 mg. Usually 50-100 mg is enough. No upset stomach, no jarring buzz, no unpleasantness…don’t really notice anything except the veil of sleepiness lifts and I have energy again. I strictly cut off caffeine use at 3 pm, so its 5-6 hour half life doesn’t interfere with sleep.
