To get started, I'd say eat an amount about the size of a pea then you can eventually find a schedule and dosage that gives desired effects. With more frequent dosing of smaller amounts, (4-6 hrs for me) you can have the benefits while keeping enough tolerance on the mental cloudiness to not get headaches/overwhelmed. There are definitely unique benefits to high-dosage meditative experiences though too.
As someone taking cannabis for breathing difficulties, when I realized I could use such a simple preparation to make it edible, it made life so much easier.
