How do people manage to take stimulants for ADHD and drink coffee with fibromyalgia?

I’m curious how some people with fibromyalgia are able to tolerate stimulants for ADHD or drink coffee. From what I understand, fibromyalgia involves central sensitization, making the body more sensitive to pain and stimuli which is why we are told to take pregabalin , and there’s also an increase in glutamate levels, which can heighten nerve excitability. Since stimulants and caffeine can increase alertness and potentially stimulate the nervous system, wouldn’t they worsen symptoms for someone with fibromyalgia since these increase glutamate levels ? If you have fibromyalgia and take ADHD meds or drink coffee, how do you manage it? Does it affect your pain levels or sensitivity?

Any insights would be appreciated!
