Dosing question, Down to 4 gpd from 20

I started taking kratom again for 2 and a half years now, I've gotten down to 4 grams a day after a couple months. I'm not looking to stop taking, just wanted to feel the effects more and not have withdrawals whenever i miss a dose.

Right now I take 1 gram about every 4-5 hours throughout the day. My question is, would it be better to take two grams twice a day, or if anybody has any tips that would be great. I'm a stay at home dad so the low energy has been getting to me lately.
