A few things that are usually comorbidities of ADHD are mental health problems (such as anxiety or depression) and eating disorders (binge eating, anorexia, bulimia) - that you may have, and meds can help you with that (or not). A good doctor can give you the pros and cons. ADHDs also have more propensity for addiction (alcohol, drugs, gambling, pornography, etc) - so being aware of that can decrease the risk. Also, ADHDers can have low self-esteem (which is something that psychotherapy can help you overcome).
Despite being expensive (a few thousand dollars), one thing that could be a good idea is a neuropsychological evaluation that can give you more awareness (and data!) about your brain.
Medications should be part (and they can help a lot!) and not the whole of your therapeutic process: a psychotherapist specializing in cognitive-behavioral therapy (usually called CBT) can help you immensely. I also invested in occupational therapy (I'm a bit clumsy, and my handwriting could be better) and speech therapy to help transform and present my ideas into words - speaking with a doctor could be a good idea to help.
You certainly have a different history: my advice is to discuss it with your doctor and find the best tools (therapy, medications, adaptations to your work environment, etc) to overcome these challenges. Some medications can also have side effects - and a doctor must evaluate if - my doctor asked me for an electrocardiogram before recommending a medication)
A sound effect that medication had on me was that it helped me to overcome binge eating, and I felt less tired at the end of a workday (probably my brain was using a lot of energy to make me focus more on meetings).
