I took my daily 16mg dose in the morning and inadvertently took another dose at 11-30pm on the same day .
My dosage was increased 3months ago from 14 to 16mg and before that 12 mg to 14mg.I did not feel any benifits from the increases -my possible side effects are aching /stiff groins. I do not know if the groin pain is from the Parkinsons or the Requip medication.
