Days one to two
The caffeine effect is immediate and often noticeably strong, particularly if you do not normally consume much. Some people feel jittery or warm, and mild headache is not unusual. Take it with food and water, and do not add your usual second coffee on top.
Days three to five
Tolerance begins developing and the subjective intensity settles. This is when sleep problems reveal themselves if the timing is wrong — if you are lying awake, the dose is too late in the day, not too large. Move it earlier before concluding anything else.

Most people have settled into a steady state. Some report the first change in the afternoon craving pattern around here. Any scale movement is water and glycogen, not fat, and should be ignored entirely — see our guide on that.
What would justify stopping
Racing heart, chest discomfort, significant anxiety, severe headache, or sleep disruption that does not resolve when you move the dose earlier. Those are reasons to discontinue and speak to a doctor, and the 60-day guarantee covers exactly this situation.
