Regarding stopping the Stamlo medicine.

Dear doctor, I had high bp around 150/80 few months ago for couple of days due to which my doctors assistant had earlier prescribed me to consume stamlo 10mg twice a day. Then after monitoring my bp the Main doctor  gradually reduced my dose to 10 mg once a day then 5mg then 2.5mg then half of 2.5 mg tablet. Now since my bp is normal my doctor said I can stop consuming the medicine and monitor my bp for one week and if it's normal I can stop eating the medicine and maintain healthy lifestyle and incase if it shoots up then I will have to be on these medications lifelong. I need your advise is it safe to stop these medicines on doctors advise. Will it have any life threatening effect on my health if I stop eating it. Please advise
