You just started the Carb/Lev?
How many times a day, or how far apart are your doses?

My dad takes 2 c/l pills 5 times a day.
He was taking it only 4 times a day, but had to add a middle of the night dose last spring.

Are you keeping in contact with your doctor?
The dr should adjust meds per your report of symptoms and lack of improvement..
Sometimes a second type of med is needed or a different med, communication with your dr is very important..
Sometimes it takes a while to get the best meds figured out for you.

Also protein eaten about same time of c/l will hinder absorption..
