Unfortunately stimulants don't have much of an affect on me so I take quite a high dose at the moment. I'm doing all the suggested things to help them along, like increasing protein, getting more Zinc, Magnesium, Vitamin D etc, staying away from citrus. Ensuring good sleep hygiene.
I see a psychologist regularly to unpick the weight of all the masking and coping mechanisms. It's a long process, but making much more progress than when I thought it was just depression and perfectionism issues.
I'm starting Neurofeedback to see if that helps and planning to use an ADHD specific performance coach in the new year to help with work.
