On Paleo I would go with around 150g of total carbs a day and if you are still at the beginning I would highly recommend to track your macros and nutritions with: https://cronometer.com/
I know, it will be an effort to track everything gram by gram, but it helps you longterm to get a feeling for your macros and also to see if you get all your nutritions during the day.
So you can easier build a habit on eating the things you need, instead of the things you like, just try it for a week or two =)
