Giveaway hopes to perk you up from the least productive time of day: 2:55 p.m.

Maybe it’s food-coma related, or the realization that there’s at least two hours more of work to go, but a study has shown 2:55 p.m. to be the least-productive time of day. 

Hoping to bounce you out of that, evian+ is giving away six-packs of its enhanced sparkling water, which they say is packed with minerals including zinc and magnesium, the latter of which has been shown to boost your brain power, right when you need it the most.

While you’re still functional at your keyboard, head on over to between 2–5 p.m. local time every day until through August 28 for a chance to have six bottles of the sparkly stuff sent right to your door, for free. 

Maybe leave a Post-It for yourself at the most productive time of day: 1:30.
