JAMESTOWN, N.Y. — Blake Tarana and family are celebrating 22 years of caffeinating customers as owners of several Tim Hortons in Chautauqua County and one in Cattaraugus, complete with varieties of hot and iced coffee, tea and energy drinks.

"Obviously, it really helps people start their day and gets them awake. Keeps them caffeinated throughout the day," said Tarana, president of TAR Enterprises.

What You Need To Know

  •  April is national caffeine awareness month

  •  A recent survey shows more than 60% of those surveyed don't have a caffeine cut-off time or drink it at least three hours before bed.

  • Sleep experts suggest caffeine intake in moderation

Whether it's first thing in the morning, mid-afternoon, or late evening, a recent survey from national retailer Mattress Next Day revealed that 55% of New Yorkers drink coffee at least three hours before bed, which is between 11 p.m. and midnight, or have no caffeine cut-off time at all.

"It's a little surprising to me, I'm not going to lie. It serves its purpose. And I think people enjoy it," said Tarana.

Like Max Doverspike, who regularly meets the guys for coffee in the evening.

"Coffee doesn't bother me at night. It doesn't keep you awake, no. Let's say I, probably have, from 6 p.m. til probably 10 p.m., I might have four cups of coffee," said Doverspike.

Dr. Jatan Shah, who heads the Sleep Medicine Center for UPMC Hospital in Chautauqua County, conducts a number of sleep studies and says caffeine is good if consumed in moderation. He says if not, the stimulant can prevent the body from falling asleep, and reduce the amount of deep sleep.

"Hence you can imagine the next morning if you don't get proper sleep, especially deep sleep your body's tired. You're just always fatigued. Guess what, people drink more caffeine, it's a vicious cycle," said Dr. Shah.

Dr. Shah says he's not surprised by the survey results, as they're a stark contrast from what experts think.

"The recommendation is about two to three cups, eight-ounce cups in a day. Try to limit the intake if possible. Your last cup should be eight to ten hours before your bedtime," said Dr. Shah.

With two of Tarana's locations open 24 hours, customers, and those on the night shift, can still get their caffeine any time.

"It's been great. We get a lot of the hospital workers, we get a lot of the cops, we get a lot of the first responders," said Tarana.

Dr. Shah also suggests caffeine drinkers who are still consistently tired, may have a deeper problem which could lead to organ failure if not checked out by a sleep specialist or a doctor.
