Vivarin, Caffeine Pills, 200mg Caffeine per Dose, Safely and Effectively Helps You Stay Awake, No Sugar, Calories or Hidden Ingredients, Energy Supplement, 40 Tablets

Works wonderfully, no jitters or anxiety but a good, steady flow of energy. No trouble sleeping at night, I take it in the morning and it gets me through the day. Very affordable, good strength. I don’t experience GI side effects that I can tell, and it helps me exercise and focus on studying, too.

Gives you the same energy as a cup or more of coffee in morning or afternoon. I hate the taste of coffee in the AM so I have been using this daily for over 30 years and for myself it definitely wakes me up quicker than coffee.

good value for the money, good energy level, easy to swallow, no pain relief.

Product good. I've always used these instead if coffee. For me, no jitters, but there is a crash once im tired.However, the seller is awful at following instructions. Maybe Amazon is packaging this up or it's being packed elsewhere, but I was promised next-day delivery multiple times and still have not received my order. Very annoying.

The product is great to keep in the glove box for driving to stay alert. However, this was supposed to be in bottle, not blister packs. They will not take this back for bottle version! Grrr😡

i work late hours so it really helps and it works

They work! Don't need to buy expensive energy drinks. Just had a baby and having to stay up at night and having to get up to go work early in the morning has sucked! These have help quite a bit to keep me alert during the day.

Normally this are a solid choice for caffeine pills, but boxes that expire in September were delivered at the end of May, giving barely 3 months before expiration. I'd expect at least a year out.This is disappointing, and if it becomes a consistent occurrence, I'll look for something else.
