I Am 53 Years Old And Have Recently Been Put

I am 53 years old and have recently been put onto BP tablets. I wake up in the mornings feeling dizzy and with a high BP reading. I am also on a Cholesterol tablet. I have constant ringing in my ears.
I have been avoiding foods containing sodium, no salt, no fatty foods, spices, sauces for the last month but it seems like it is not working as my BP is rollercoasting
