Exam week caffeine afternoon cutoff sets a personal last-caffeine time—often noon to 2 p. m.
for sensitive sleepers—so six-hour half-life caffeine does not delay sleep before early test days. Late study sessions tempt second espresso; swap to water, herbal tea, or a protein snack when focus fades.
Genetics and pill form change sensitivity. Protecting seven-plus hours sleep usually beats an 8 p.
m. latte for next-morning recall.

-
What time should I stop caffeine during exams?
Many sensitive people aim for noon to 2 p.m. last dose before early exams. If sleep latency stays long, move cutoff earlier for one week and compare morning focus.
