I have many patients who do great on 60-90 mg of Adderall per day and have for up to 13 years. Anybody like yourself who is not doing well needs to make changes. You need to start with a re-evaluation with a physician.
One simple option may be to change to the new Vyvanse and possibly just one/day (70mg).
Many of my patients require Tenex with Adderall. Patients on Vyvanse are much less likely to need it.
One of the most important things I learned in training in the ‘60s – if what you are doing isn’t working, do something else, even if it is wrong it gets you unstuck.
Some important lifestyle issues to consider include: quality sleep, exercise, bright light every day, good diet, omega 3 fatty acids, and possibly Cerefolin, and personality issues. If you need medication work with your doctor until you find “the right medication at the right dose” for you.
