For Drowsiness "I have ADD and I'm super sensitive to caffeine and so when I split this pill and half starting at 6:30 a.m. before work it lasts until 4 p.m. and at 4 p.m. I take the second half and I could be up until 1 a.m. but I'm capable of getting myself to sleep before then. I personally love it. I hate coffee I hate the acid reflux of coffee, and I hate the staining of teeth which this removes. Obviously this isn't recommended for everyone but I am a 30 year old female and it helps me keep attention and stay productive at home otherwise I would be a chill zombie."

For Drowsiness "I suffer from severe OCD and experience debilitating lack of focus and attention because of it. I'm usually stuck in my head and it makes it hard for me to stay in the present moment, which can be very stressful for me. However, nodoz helps me focus and get out of my head, which quietens the OCD thoughts and compulsions in return. I'm not sure why though, most people get worse OCD symptoms if they are on caffeine but I barely consume caffeine so when I DO take a nodoz tablet, it affects me positively. It's almost like a lifesaver when I'm experiencing a bad OCD day. Nodoz is best to take in the morning or else you will not be able to sleep before bed :) I only need to take one for it to work, sometimes two."

For Drowsiness "I've used NoDoz plenty of times in the past and would highly recommend to those the need a midday/afternoon energy boost for work or study. I would usually only take one tablet a day when I do use NoDoz and usually within 30min-1hrs I start to feel the results, keeps me awake, focused and energetic while on the job. There are some negatives with NoDoz though: -if you take them too often their effectiveness starts to wear off e.g you will still feel tired and not alert but you won't be able to sleep. -NoDoz can interrupt your sleep and keep you awake during the night -would alway recommended having plenty of water while using NoDoz otherwise you may start to feel dehydrated and may lead to headaches"

For Drowsiness "For some it doesn't appear to work the same and maybe they have a large caffeinne intake to start with. I just have 1 morning coffee a day and I find "No Doz" excellent for me. I won't travel without taking at least 1, I can feel confident I can get to my destination in an alert and safe driving manner and I enjoy the drive. Occassionally I will take one just prior to lunchtime to help me get through the working day, it's an amazing pickup for me."

For Drowsiness "NoDoz is the only medicine I can take that helps with my periodic fatigue and sleepiness during the day. One pill around 10 a.m. gets me going to complete my most stressful job. I don't take daily but when I did, I could instantly see the difference."

For Drowsiness "So I drive trucks and I have to drive different times of the day. A friend told me to buy NoDoz and it didn't work at all when I took this medication I was instantly tired and I almost fell asleep at the wheel so I definitely do not recommend this at all to try to stay awake"

For Drowsiness "Never again will I take this medicine!! The recommended dosage isn't listed on the packet that contains two pills so of course I took both. I ended up with chest pains that lasted almost 6 hours, nauseated, sweating, headache an to top it off paranoid that I was overdosing and going to have a heart attack! I'll stick with coffee from now on, definitely don't recommend it!"

For Drowsiness "I drive at night, it gets to like 9:30 or 10pm and bang! Drowsiness hits me like a sledgehammer! I feel like I've been drugged, something pulling my eyes shut. So a friend suggested No Doz, took one pill... Nothing. 2hrs later took another... started feeling dizzy as anything, then nauseous and still falling asleep. In fact, if anything it made the drowsiness even worse! Felt dizzy and sick all the next day. Will never touch them again, ever! Gone back to drinking RedBull."

For Drowsiness "I’ve just taken my first one today, about 2 hours ago. I have severe depression and chronic fatigue so I’m just trying to see if they’ll help at all. I’m certainly more awake than I’ve been the past week, not particularly energetic but definitely an improvement. As someone who struggles to move without a redbull this is definitely far cheaper than 5 a week at 5 dollars a can. Caffeine never had a strong effect on me so I’m going to take another and see how it goes."
