You cannot control HPPD.
I have eye floaters and I can live just fine with them jumping around, still doesn't change the fact they are annoying and if I could get rid of them I would; if they were caused by something I did and I could change that, I would.
I'm sure most people with HPPD, if given the choice, would never have done psychedelics in the first place; HPPD is why I stayed away from psychedelics.
