Talk to General Physician on Rise In BP After Sleeping

I want to ask about my Blood Pressure. Issue is that throughout the day my BP remains normal and I feel okay.. but as soon as I go to sleep my bp rises (150+/100+) which results in waking me up and I feel pain in my head like someone is pulling my pain in chest too, and extreme Anxiety.. then after 10 to 15 minutes it goes away and BP becomes normal again.. I took several medications for it and this issue resolved with medications and it used to lower my BP about 90/50 at night time also but my doctor said I don't have to take those anymore since the issue resolved. But after a week of leaving meds, I'm facing the same problem again. It only happens at night after I sleep, that too for some time only and everything remains normal at Day time. Kindly tell me what could be the possible reason for it.. I've performed ECG and the reports were fine. My current weight is 76 kg, Height 5'8".
