The Lock In Stack is built for the people whose days run long. Lock In pairs WorkMode ON for the morning with three tubes of Power Hour for the afternoons that need it. Deep work, back to back.
Citrus Rush and Raspberry Rampage cover the morning and the back half of the day. Zesty citrus to open. Tart raspberry fizz for the afternoon. Two flavours, one routine.

Lock In
One tub. Three Power Hours. Zero excuses. Your WorkMode tub handles the daily rhythm. The three Power Hours are for the days that don't play along: the deadline, the double shift, the meeting that should have been an email but somehow became a whole afternoon. Keep them in the drawer. You'll know when.
