I'm a software developer. I've taken adderall for the last 15 years. I have ADHD. Adderall changed my life for the better. I thought ADHD was bullshit until I saw the difference adderall made in my life. I don't function without it. I don't see it as a performance booster or a productivity aid. For me it's a necessity. It's the difference between remembering to pay my bills and having my car repossessed even though I had the money (true story). Negative side effects... I have an essential tremor. The adderall makes it worse. Eating peas is a frustrating experience. Beyond that, nothing. I wish it curbed my appetite, but it doesn't. I wish it gave me superhuman coding skills, but it doesn't. For me it enables me to hold a job. I understand that it's a different experience if you don't have ADHD. Friends tell me that they buzz. Their heart pounds. It's speed. None of that is true for me. I take 60mg XR daily. At this level I'm a functioning member of society. Nothing more.
