Numbness in legs and hands, weakness? the spoon in my hand didn'...

I have been taking 100mg Januvia for about 4 months. It gets my blood sugar numbers down, but not enough. I have noticed that starting with the 4th month of taking Januvia, my blood pressure has been up. I previously had no problem with high blood pressure. I am nervous to just stop taking Januvia, so I have started taking high blood pressure medicine.

I have 2 questions. Has anyone had problems with high blood pressure since taking Januvia? Does anyone know of an Alternative Medicine (herbs...etc) that really helps lower blood sugar?

I am having trouble myself with numbness in legs and tigling and back of legs and butt burning. I was find until I started taking Januvia plus my legs feel cold too. I called doctor and told them I was stopping it. I was only on it for 15days. Plus my bllod sugar levels went up a little on it too.
