I've been taking Prestiq for more than one year for palpitations.It helped me a lot. The big question is that how to wean off this med if no smaller doze is available than 50 mg??? My doc said just half it. It's not right to crush coated pi I've put more than 50 lb which makes me consider weaning off this med. I had very rough experience when missed my doze once-vertigo, nausea, anxiety and high BP . My doc says I should half my doze. Is it appropriate to cut this pill?
