How to stay safe from things like hppd?

So, i have pretty good experience with lsd, have been doing it since last 2-3 years and done upto 380ug easily without any issues multiple times.

Now, it sort of doesn't feel exiting and I feel like maybe I should up the dose but scared because of things i have heard about hppd, psychosis and other scary stuff.

I only drop once in two/ three months and its mostly just 1 light blot or something for events.
