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've only been taking it for 3 days, but I can understand now when people say they feel it running in the background. So far, no side effects other than appetite loss. I do feel energy from this, but not like Adderall, there's no anxiety tied to the energy. It's more like motivation than energy. One thing I've noticed is that I like to always be doing something productive in some way. It's not the type of energy you get and use to dance or work out, you feel driven to get things done. It lasts for the whole 16 hours, which surprised me, I'm an ultra-rapid metabolizer. I have no crash on this like I did with Adderall. I'm just waiting for my period now to see how the cramps are and giving the medicine more time to see if I do have any side effects. So far, none, but no appetite."

For ADHD "I am diagnosed with Concurrent Concussion Syndrome with ADD symptoms. I took Vyvanse for over a year, and I thought I loved it, until I realized it gave me anxiety because I was trying to cram 16 hours' worth of homework and chores into the short period of time the medication worked. My neurologist had me switch to taking Mydayis, and I have loved it because I do not feel the 'high' that Vyvanse gives you, and in turn, I also do not feel the medication slowing down either. Now, I still take it at 5:30 am, but I can do homework or concentrate on other tasks well past 8 or 9 pm. Advantages: - long-lasting - continuous feeling throughout the day (no ups and downs) Disadvantages: - makes me not feel hungry - loss of appetite can make low blood sugar hit me all at once if I forget to eat - if I sleep in on the weekends, I can't take it because it will last too long. Hope my experience helps! I would definitely recommend it to anyone looking for longer-lasting stimulants, but I know that everyone reacts to things differently, so it might not work for you."

Frequently asked questions

For ADHD "I've tried several ADHD meds, and Mydayis has definitely been the best for me. I'm on the lowest dose, and it starts working 20-30 minutes after I take it. I'm then able to be productive and direct my focus easily, compared to other meds (e.g., Adderall), which gave me a burst of intense focus that I had no control over. The transitions are barely noticeable, and it really helps maintain consistent energy levels. After wearing off, it's a very natural 'I've worked all day, and now I'm ready to relax before bed' feeling (no crash). I also noticed it significantly helps manage my depression-something no other ADHD med has done. The only downsides: (1) it does reduce my appetite a lot, and (2) it only lasts about 9-10 hours on my current dose (12.5 mg), but higher doses (25 mg+) give me headaches. It's not perfect, but the positives definitely outweigh the negatives for me. Lastly, you don't know how it'll affect you, so don't let reviews scare you away if you/your doc think it might help."

For ADHD "I’ve been on Mydayis @37.5 mg for a year now, and I really liked this med over the others I’d taken. Before Mydayis, I tried Vyvanse, Focalin, and Concerta, and while all of them caused decreased appetite and weight loss, Mydayis never makes me crash or feel anxious, so it’s the best one so far. It gives me a big boost of energy, and I can get a lot of work done (a little obsessively, but still). Warning though, the withdrawal symptoms for me are god awful. If I miss a dose, I will sleep non-stop (multiple 3+ hour naps throughout the day) and eat just about anything in sight. Generally though, Mydayis has been a very good fit for me, and I wouldn’t be able to keep up academically without it. I know a lot of people don’t do well on this ADHD med, and it definitely isn’t for everyone, but I really would try it if you’re struggling to find a good fit! Kicks in very fast and lasts all day."

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 "Taking 37.5 mg for a few months. Previously on 70 mg Vyvanse + afternoon boost. Good: Slows down my racing thoughts. Focused for a few hours. Low appetite - def can lose a few :) Not good: (v = same as Vyvanse) I think my eyesight is affected - v. Dizziness periodically - v. Increased BP - v. Nail biting. Jaw clenching - v. Sweating. This med is going to be like all the others out there. Good for some people and not good for others. With any med, if the side effects overshadow the benefits, then it isn’t for you. Mydayis works like Vyvanse, but initially didn’t need the boost. When I take it at 6 am, I have to get right up and move around or I’ll go into a deep sleep and wake up 1-2 hrs late for everything! I still can’t figure out if caffeine helps or hinders it. I’m going to give it a few more months to see if I need to increase or go back to Vyvanse + boost. All of these meds should be accessible. No one should have to change just because of cost, in my opinion."

For ADHD "What's throwing me off is seeing many experiences saying they couldn’t feel Mydayis working for 4+ hours. It starts off with a small instant release, so I do feel mine working right away. Side effects are different for everyone, but for comparison purposes: Adderall XR 30 mg worked 6-7 hours, then sleepiness and a hard coming down/depressed feeling, loss of appetite, calming effect - helped rationalize my emotions effectively. Mydayis: 12 hrs, still feel working within first 30-60 mins like Adderall, my appetite came back with this, no coming down feeling, but the overall effectiveness of helping with focusing sometimes isn’t as much. I’ve thought about increasing, but I’d like to see about therapy for self-management or at least a low dose. The doc also said if this dose doesn’t work as well that we’d switch to Vyvanse, which is one I haven’t tried, so I’m afraid to switch. Overall, this one has worked best for me, but I am looking at healthier avenues in the near future."

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 "10 days into Mydayis. I have no appetite even in the AM before I take the Mydayis, 50 mg. I have to force-feed myself, even ice cream is a struggle after the 3rd bite. After I take it, I feel lost, can't track conversations, no/minimal recall, I can't even prioritize. My production at work is half of what it was when I was on Vyvanse 60 mg. I don't have any motivation. I want to do things, I just can't. All the feelings of being lazy, feeling bad about myself, despair, and no motivation have come back. I feel agitated and feel that I get angry much faster. My anxiety is worse than it was when I was on Vyvanse. I am constantly bouncing 1 or both of my legs and only bounced them a little when I was on Vyvanse. I am calling my Dr. 1st thing in the morning, and I hope that she puts me back on Vyvanse. There is a shortage of Adderall and Vyvanse right now, so I am hoping I can get it. While Mydayis is only about $3 a month, it isn't worth the savings."

For ADHD "Switched from Concerta to Mydayis for the longer duration mechanism Mydayis offers. Was started on 25 mg of Mydayis. ADD symptoms improved, but I experienced dry mouth, dizziness, heart increase, and appetite decrease, which subsided after the first week. Second week, I felt like the dose was not effective. Doc switched me to 37.5 mg of Mydayis, and so far symptoms of ADD improved, but side effects are rough. Dry mouth, headache, dizziness, lack of appetite, increased anxiety. I’m on day 4 or 5, so hoping the side effects subside when my body adjusts to the higher dose... fingers crossed."
