Hypertension nocturnal. Please advice.

My BP in the night increases to 155/102 and prevents proper sleep. I try to meditate but it increases more. Currently I was having dilnip tm50 in morning and dilnip t40 around 5pm This was unable to control. When I took an additional dilnip 10mg before sleeping it is ok. Recently doc changed my medicine to stamlo 5mg twice a day and metxl50 in the morning. This does not seem to be working because the early morning bp is still high. Prevents proper sleep even though I have started to eat early and sleep around 10pm Have control on diet and salt and do walk every morning 3 months back i had to undergo a nephrectomy due to large cyst in left kidney. Right kidney is working well. BP is worrying. Please advice.
