For ADHD "I am so thrown off at how many positive reviews I have seen on this stuff, however, I must have an insane pH balance (causes amphetamines to become ineffective), but I do not see how it is possible to take the highest dose they provide and not even feel anything... like I have not taken anything at all... The other night, I got so tired that I fell asleep without warning!"

For ADHD "Disappointing, oh so disappointing. Used to be on Adderall XR and loved it. When the doctor told me I could not go up on the dosage anymore, I had to switch to Adzenys. Starts great at first, but after the second month, I started feeling very lethargic the next day. Then I started to oversleep for work. Started with 30 minutes, and then it jumped to 2 hours. He had to prescribe me another medicine with Adzenys for it to stop the lethargic response, which was Qelbree. So I take that at night. The Adzenys works, again, but it makes me more tired, and I don't feel like I am focusing on my priorities, but I focus on more fun things about me, and only things that I feel like doing."

For ADHD "I was on Vyvanse 70 mg and switched to Adzenys because I felt the Vyvanse was not working as well. I take 18.8 mg and feel this medication makes me tired and does zero for my ADHD. I am 51 years old and found out 18.8 is for children, that 12 mg is the highest adults should be prescribed, so I will talk to my doctor, but Vyvanse worked much better."

For ADHD "Evekeo made me feel like I had the flu. I felt like I had stayed up until 5 a.m. drinking tequila. I had had no alcohol at all. My muscles ached, I was exhausted, I felt like I was going to puke, and I could barely move. I went back to Vyvanse after 2 days. It ends too early for me, but doesn't make me miserable."

For ADHD "Okay, so I started taking this medicine after switching around meds since I was about 7, but this medicine is by far the worst. When I forget to take it in the morning, I suffer and have terrible tiredness. I have no energy. It’s especially bad since I’m a lifeguard and have to be alert. I wouldn’t recommend taking it. You could go to bed at regular hours and still wake up with no energy at all. Don’t get it twisted, the medicine was great at first, but as time has progressed, I notice more and more side effects. The most prominent one is having a lack of energy during the day."

For ADHD "My child was just recently diagnosed with ADHD, and first we tried Adderall. It seemed to just make him tired, but it helped a little bit, but not enough. So then we tried Dyanavel - this stuff turns my kid into a possessed little... (mmm, what word would be good here? He definitely wasn't nice!). It started off very good. He was listening, and everything was going well, then about 4 hours after he took it, he got in a little trouble for not closing a door. It was just a simple 'Hey buddy, come close this door...' and he FLIPPED! He looked at me like he was going to stab me in my sleep and started throwing a little baby tantrum. And ever since then, he acts like this every time he gets in trouble. He whines and throws a huge tantrum. He is 7 years old and does not do this without his meds. I know it's different for everyone, but from my experience, if your child has ADHD and has trouble focusing and listening like mine does, I do not recommend this medicine. We will be trying something else."
