My Mother 82 Years Has Restless Legs And Wears A

My mother 82 years has restless legs and wears a c-pap at night with 2L O2
She has mirapex and tramadol ordered. She takes the mirapex daily but recently
Has had new symptoms of increased restlessness and the need to take an extra mirapex around the 6 pm hour. Is she experiencing side effects from the Med or does she need an increase in the dosage??
