For ADHD "I was prescribed 30 mg XR of Adderall plus 20 mg tabs per day, my doctor switched me to one 25 mg Mydayis, and it was horrible... well, it was horrible because technically it was a very dramatic decrease in dose. After a week of being down, tired, foggy, and emotional, I called my doctor to increase. I honestly think 50 mg of Mydayis is comparable to 30 mg XR Adderall, but lasts longer."

For ADHD "Taking 25 mg right now and was on Adderall XR 30 mg. I don't understand this medicine since it usually makes me tired and down for about 2-3 hours after taking it, then get an okay amount of focus for another 6-8 hours. I personally can't deal with those 3 hours every day when I need to be productive, so I will try something else. This drug may be very similar to the chemicals in Adderall, but it definitely does not feel like it."

For ADHD "I was prescribed 50 mg. 1st day I could literally feel the release of the medication. During the lag of the release, I would get headaches, become tired, irritable, and frustrated with every situation and conversation. By evening time, I couldn't carry a conversation without forgetting prior known facts. Saturday, I was completely not myself. On top of how I felt Friday, I was emotional, had down thoughts, I couldn't follow a timeline: I was late for everything. Sunday seemed to be better but not by much. Monday... horrible, it was like I added Friday and Saturday symptoms together, then add in horrible chest pain, shortness of breath, constant feeling of about to faint, fever, flu symptoms, hot/cold, exhausted but not able to sleep, & more symptoms. I refuse to take another dose."

For ADHD "Today was my first day on Mydayis 50 mg. I was taking Vyvanse 50 mg, but it was only helping for about 4-5 hours, then wearing off. Today I could really tell the difference in my concentration/focus and my energy; it was much better. I did, however, feel tired about an hour to two hours after taking it but then got motivation after that for the remainder of the day. Like I said, my focus was better; I wasn't running around my house like a crazy woman, starting a ton of tasks and finishing none. I was able to get things accomplished pretty easily today. I am remaining hopeful that Mydayis will continue to work for me."

For ADHD "It takes too long to kick in, I have to get up hours before I am supposed to just to take it so I am alert at work. I was just sitting here today trying to figure out why I have been so tired and sad, and I started reading the side effects, and now it all makes sense. I am going to keep taking it until my month is up, and if it doesn't get better, I am going back to my Vyvanse and Adderall."

For ADHD "I was on 70 mg Vyvanse for several years, but was constantly complaining that it stopped working by 2 pm every day. So when Mydayis came out, my doctor suggested I try it. It DOES last longer, but that also means constantly being 'on' from the time you take your pill to the time you fall asleep. This led to a non-stop feeling of being overwhelmed and worsened anxiety. I was stuck in a state of exhaustion but never able to rest. I started at 32.5 mg and didn't feel it was helping me concentrate, so I went up to 50 mg and still didn't feel like I was concentrating well. The worst issue I had is a much higher diastolic blood pressure - I'm talking after 4 months on Mydayis, I was 15 points higher than before I started it. Additionally, I started grinding my teeth and clenching my jaw, leading my dentist to comment on some chipping of my teeth from grinding. I'm switching back to Vyvanse. Mydayis is not worth it - be careful what you wish for, I guess!"

For ADHD "I’ve been on Mydayis 37.5 mg for a week after taking two and a half 20 mg Adderall for four years. I feel slightly more focused for a few hours longer than my first dose of 20 mg Adderall but much, much more tired. I find myself looking for sugar or caffeine to keep focused at work after five or six hours. I don’t know if the dose is too low or it’s just not for me. Hopefully, at my next appointment after trying it for 30 days, my PCP will have some answers or suggestions! I don’t want to gain weight!!"

For ADHD "Tried for two months. This stuff is horrible. My eyes itch, my stomach hurts all the time, and I never feel like I am getting any benefit. I could fall asleep after taking this medication. I am more tired than alert. I will be asking to go back on Vyvanse."
