For ADHD "I was on 30 mg Adderall XR for about a year, which worked well for me except for the crash. It became much less effective at that dose after being on it almost a year, but my doctor has a cap on the Adderall dosage she will prescribe. Just switched to Adzenys 12.5 mg at my last appointment. I've been taking it for almost a week. I'm completely unfocused and back to having trouble getting to sleep. Not that it does nothing at all...mostly I just feel like I'm in another world. My thoughts are definitely slowed down, but more distracting from reality. I'm definitely feeling really chill overall. It does last longer than Adderall, if you want to feel like you're in another worldly state for 12 hours or more. Things affect people differently, and I'm sure this is very helpful to a lot of people, but I tried to Google similar experiences and found none, so I wanted to write a review in case anyone else might be experiencing the same."

For ADHD "Recently, I switched from taking Adderall to Vyvanse and then to Adzenys. I have been taking short-acting Adderall tablets on and off for the past twenty years, twice a day. I tried Vyvanse hoping that it would last longer during the day, up to twelve hours. Unfortunately, I experienced terrible side effects, such as mood swings, insomnia, and zero focus. I tried doses ranging from 40-70mg and spent six months on it, only to switch to Adzenys. I started taking Adzenys last month, and it is more like Adderall. It provides a mellow focus and does not cause additional anxiety. However, it only lasts for about six to eight hours, and my doctor is hesitant to prescribe it twice a day. We are increasing the dose this month, and I hope it is more effective. The packaging is inconvenient, but the medication works, and the carry case is nice and fits in my locked bag for safety. The easy-to-take tabs are definitely a hazard around children because they look like candy or something. However, if you are responsible for your medications and keep them locked up for safety, it should not be a problem. The pharmacy takes a long time to restock it as well."

For ADHD "Adzenys 15.7 mg was my saving grace. After a bunch of trial and error and months of trying other ADHD medications that never worked, I was ready to throw in the towel. I was up to a high dose of Adderall daily that I had never felt anything with besides painful crashes, and Strattera made me feel wired and foggy. Adzenys was my perfect puzzle piece after constant frustration with Adderall somehow never working and Strattera inducing severe anxiety. Adzenys is a subtle jerk forward for me and doesn't wire me too hard on things to the point of being antisocial and anxious. I still feel like myself on this medication, just a version of myself that strives to be productive and aim for better habits. That being said, though, my task initiation isn't really there, but once I get myself to sit down and start one, I can controllably focus on it to the degree I want. It is definitely extended release and can feel it hit at random times harder than others, but I've never had a painful crash."

For ADHD "My insurance no longer covers Vyvanse (70 mg), which has worked wonderfully for me over the last 6 years. My doc gave me an Rx for this, along with a coupon that makes it cost only $35. I took it for the first time this morning, and I hate it!!! My body feels cold, ears are ringing, and I can't focus to save my life. I just want this stuff out of my system."

For ADHD "I just started this medication, and I like it for the hyperactivity side of my ADHD. I have tried almost every ADHD medication, but most recently was on Vyvanse. With Vyvanse, I had great concentration, but the hyperactivity was not controlled well, so she had me try Adzenys. I've only been on it about a week, and the taste is not that bad for being a dissolvable medication. But I will say that I can't take it immediately and then go to work because I become almost spaced out. I know I probably need to adjust to it, and it's great once the first hour has passed. I'm still unsure whether I will stay on Adzenys or switch back to Vyvanse, but so far, so good."

For ADHD "I was prescribed this after my pharmacy was out of Adderall. Well, I felt so spaced out and just stuck. I literally couldn’t get one thing done. Couldn’t even hold a conversation! After a couple of hours, the feeling subsided, but because it was an extended release, a few hours later I felt the same. Only took it for about seven days. I have a pretty busy job, so there was no way I could remain in that state of mind. Awful. Waiting for the next appointment for a different prescription. Hopefully back to Adderall."
