l citrulline and l arginine dosage question

I’ve been taking 10G of l citrulline and 5G of l arginine everyday for a couple of months now, and I’m just wondering if that’s too much?

And I also feel my body has gotten used to the dosage that I at least think I’m not getting the full effects of it. Should I take a break of it or increase dosage? Or I might just be going crazy and still getting the full benefits of it
