Not to be aloof or contrary here, but why not ask the prescribing physician? Ace inhibitors do not have the requirement, as beta blockers do, regarding a methodical, slow wean, but your body is used to this medicine, after 4 years. Common sense would tell me to give my BP control system a little time to adjust. I am very cautious with BP medications.
Glad you could stop it
Good day to all,
