Built for the Graveyard Shift: LSC100 + Night Shift, Gaming & Gym Energy
Curated by The Dose, by LSC100® 15 cards Updated Nov 2026
Night shift nurses, long-haul drivers, gamers grinding past 2am and 5am lifters all run on caffeine. This stack pulls the research on doing it right: when to dose on a night shift, why energy drinks and stacked pre-workouts backfire, what caffeine actually does for esports reaction time, and why caffeine plus a short nap beats fatigue behind the wheel. Sources are NIOSH, FMCSA, NIH, the Sleep Foundation and peer-reviewed studies. LSC100 is a dissolvable lozenge with 100mg caffeine and 100mg L-theanine, sweetened with isomalt and stevia. No water, no shaker, no can. It fits in a gym bag, a scrubs pocket or a cab console.

CDC's NIOSH training for nurses: caffeine takes about 30 minutes to kick in and has a 5 to 6 hour half-life, so a dose late in a night shift can wreck the sleep you need after it.
Sleep Foundation guidance for night and rotating shifts: take caffeine early in the shift, in moderate amounts every one to two hours, and stop three to four hours before you plan to sleep.
Peer-reviewed study of hospital nurses working three straight 12-hour shifts: sleep averaged about 5.5 hours between shifts, sleepiness built each shift, and caffeine use was heavy.
Federal trucking safety guidance: alertness drops with time of day, especially after midnight, and caffeine only buys a short window. It is not a substitute for sleep.
Loughborough sleep lab study: 200mg caffeine taken right before a short nap cut sleepy-driving incidents far more than caffeine alone. The classic caffeine nap evidence.
Review in Occupational and Environmental Medicine: cold air and a loud radio only help briefly. The effective move is to stop for a short nap or about 150mg of caffeine, and both together work best.
Dose-response study of 24 first-person shooter players: caffeine improved clicking accuracy, target tracking and reaction time compared with placebo.
Crossover trial in Scientific Reports: elite FPS players given 3mg/kg caffeine an hour before play showed faster reactions and better kill ratio and accuracy.
2026 systematic review coverage: more than three in four esports supplements studied contain caffeine, and pure caffeine showed the most consistent gains in focus, mood and gaming performance.
Hacettepe University trial comparing caffeine alone, caffeine with L-theanine, and caffeine with breathing work on gamers' reaction time and accuracy. The same two ingredients in every LSC100 lozenge.
Baptist Heart Specialists: loosely regulated pre-workouts can stack high caffeine with other stimulants, and dry-scooping adds choking and tooth-enamel risks. Read the full label before you lift.
NIH's NCCIH fact sheet: energy drinks vary widely in caffeine, can pack more added sugar than a full day's limit, and are linked to sleep problems, anxiety and digestive issues.
