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

I just started taking these and the first day I noticed a great improvement in my alertness and I feel energized. I like how I got the blister pack because it is easier for me to store in my purse or some place a bulky bottle won't fit. I took one pill and it lasted for hours. I highly recommend this if you need to get work done or want to be awake and just enjoy some time to yourself if you couldn't before because of tiredness.

I have been using caffeine pills for about 45 years.I don't like to drink coffee because it takes so long to help me wake up and also makes me have to go to the bathroom a lot.I take a vivarin after I wake up and I'm wide awake and ready to go in about 20minutes.

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.

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😡

Product is stellar, however they have a short expiration date.

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

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.
