For ADHD "I have had ADD my entire life (I'm 30), starting treatment with Dexedrine in kindergarten. I've tried literally every ADD drug there is except Zenzedi and Desoxyn (methamphetamine HCL). I've even tried modafinil. Chemically, Vyvanse, Dexedrine, and Zenzedi are the same, just with different absorption. Adderall is 80% Dexedrine with 20% levoamphetamine, which is more physically stimulating than dextroamphetamine. If you are like me and hate stimulants because of the crash at night and morning exhaustion, I need a drug that lasts all day and is smooth, then consider Mydayis. I only wrote this to help anyone who's considering Mydayis. I would never waste my time helping any pharmaceutical company with a review. Mydayis is unique and different from Adderall and the other dextroamphetamine stimulants because it has amphetamine in addition to other Dex salts. Give it a try. If you have trouble with insomnia from taking it, then your dose is too high. Just drop it. Good luck."

For ADHD "I have been taking Mydayis 25mg for 2 months, and I have experienced ZERO negative side effects. I was previously prescribed Adderall XR & IR and Vyvanse. Those medications were somewhat effective; however, they came with a lot of side effects (loss of appetite, moodiness, insomnia, heart palpitations, dry mouth, dry skin, and anxiousness). The best thing about Mydayis is the way in which it feels 'natural' and the way it steadily tapers off throughout the day. With previous medications, I could actually feel the effects coming and going and I would get these sensations of feeling 'high.' With Mydayis, I never actually FEEL the medication taking effect, but I can tell a HUGE difference in my performance, mood, and ability to focus. I even feel relaxed, as if my mind can finally make sense of racing thoughts and feelings. I usually take my medication around 8 AM and I am easily able to fall asleep by 11 PM. With Mydayis, My Day Is manageable!"

For ADHD "I started taking Mydayis 25 mg 5 days ago, and I really like it so far. I was on Vyvanse for the last 3 years and eventually built up a tolerance to it. I like how Mydayis doesn't give me that 'nervous, heart-racing' feeling like Adderall and some of the other drugs do. It's not going to give you an intense rush but provides a steady, long-lasting feeling of alertness and focus. It doesn't affect my appetite, sleep, or mood."

For ADHD "My insurance company didn't want to pay for it, and I read that it has the same ingredient as Adderall. So my doc prescribed Adderall XR twice daily. It works fine for me. Use online coupons and save up to 60% of the regular price. Most doctors think if you take it twice daily, then you'll have insomnia. But if you take the second dose at least 8 hours apart, then you should be fine. I've taken one dose 10 hours apart and still fell asleep, and my mind was at peace. Don't suffer if you are in need of help for ADHD. And I'm not here saying this medication is bad. I just want others to know that if you can't get this med, then try what I've done. Don't give up hope."

For ADHD "It's helping with talking too much, binge eating, organization, memory, motivation, prioritizing tasks, memory, breaking hyper-focus, listening, conveying thoughts, studying, homeschooling my preschooler, staying awake all day, sleeping all night, and my organization is creating more structure for my kids. I have everything ready before they wake, so we're not fighting before school. The best part is I'm feeling more energy, so I'm walking the dog, actually wanting to play with my kids outside, and my libido came back! lol Unfortunately, it didn't take away my anxiety and irritability as much as Vyvanse did. Only side effects I've noticed: I need to up my fiber intake, and I have dry mouth (water bottle in purse, gum, and a fluoride mouthwash to keep my teeth healthy - these things seem to work great). The first 2 days at night, I felt so cold, it took me a while to fall asleep, and I couldn't stop scratching my scalp - so weird! Other than that, it's working great!"

For ADHD "I received Mydayis 25 mg 2.5 months ago for severe combined type ADHD (also started Lamictal at that time). After taking the 25 mg dose for 2 months, I was not impressed. Mydayis seemed to work OK when beginning Lamictal, but the effects declined as the Lamictal titration from 25 mg to 200 mg maintenance dose. The benefit of Mydayis was increased alertness on the morning commute to work and a general calming. My focus and concentration remained impaired. The Dr bumped Mydayis to 37.5 mg and feel calmer and less impulsive, and alertness is increased to the point of insomnia. No relief of concentration or problems forgetting things, losing items, etc. In fact, I feel quite depressed and drugged."

For ADHD "I was prescribed Vyvanse chewable 30 mg in the AM and 30 at noon. I loved it, but had a month where I didn't take it regularly at noon. Dr. suggested this because of the extended release. Two weeks in: my sleep is concerning. I haven't hit REM in three days now. I have no appetite, even in the AM before I take the Mydayis. I have to force-feed myself, even ice cream is a struggle after the third bite. The two to three hours after I take it, I feel lost, can't track conversations, no/minimal recall, I can't even prioritize. After those hours, things level out a bit, but I don't have the motivation I had with Vyvanse. I believe there is a link between loss of quality sleep and struggling to meet my dietary requirements and how the drug affects me."

For ADHD "Pretty bad. In fact, this is the worst ADHD med I have taken since Ritalin. It lasts longer? Well, it takes like 3 hrs for it to kick in, and when it does, the effect isn't that strong. That same effect lasts for about 6-8 hrs, then it drops hard. Side effects are hilarious. I get the shakes, tingles, drowsiness (even right after I take it), itchiness, inability to sleep. That sounds like a crackhead. Pros are that my appetite has been decent, I'm more social. It's almost like I didn't even take anything. Take Vyvanse if you want to focus. It's smoother and stronger. This is a dirty drug for me."

For ADHD "I've been taking Mydayis for about 2 weeks. I was diagnosed with ADHD 7 years ago and took Adderall XR 30 mgs + 10 mgs every day. Even though it helped me in many ways, it also made me antisocial, anxious, overused it sometimes, and very thirsty at all times. For those reasons, I decided to try something else (Mydayis 37.5). Honestly, I feel much more motivated, my energy increased, I'm no longer antisocial, no crash, and, most importantly, I can focus well. For about a week, I had some side effects (increased heartbeat, couldn't sleep, couldn't focus well, high BP), so give it some time to adjust. I also read that most people who switched from Vyvanse to Mydayis are suffering from depression. Be careful."

For ADHD "Mydayis was the most effective drug I have ever taken for my ADHD, and it worked too well. It is very good for getting any kind of work done, but the side effects were so insanely negative that I could not handle taking them any longer. I was prescribed Mydayis 25 mg, and I would take it on the weekdays for school and sports to stay focused, but it had really affected my sleep, my appetite, my mental health drastically declined, I could not think rationally, and I was so irritable all of the time. The Mydayis had worsened my depression, anxiety, and would trigger me to pick my eyelashes and eyebrows (trichotillomania). While it had me wanting to do my work and I was finally motivated, I simply could not take the side effects anymore."

"I’ve been taking this for the last three months because generic Adderall has been out of stock. This helps with narcolepsy a little, but it is way less effective than Adderall. It’s better than taking nothing at all and trying to stay awake. One positive is that I don’t suffer from insomnia as much as I do when taking Adderall."

For ADHD "Caused increased irritability and insomnia. Having to wake up early to take the medication because it lasts so long is very frustrating, especially when it causes insomnia. I started getting up at 5 AM to take it and still wasn't able to fall asleep until after 1 AM."

For ADHD "I'm eighteen years old and was taking Concerta (54 mgs). I decided to try this (50 mgs), and wow. First night, absolutely no sleep, tossing and turning constantly. Second night, I was able to get in about 5 hours even though I took the medication at 6 a.m. and tried to go to sleep at 12 a.m. Third day was actually good, very focused and felt decent. But that night all hell broke loose. Tossing and turning again, and started thinking I did things that I really didn't do. Needless to say, not a fun time."
