Are you forced to tremor at times once you start?

I mean that in the way, after I did the first times with the exercises, will the tremors always happen when I relax or at point of my life ? It’s one thing that makes me nervous about starting. If it happens when I want it to happen, it’s perfect, but i wouldn’t want to be blocked because tremors happen when I didn’t plan them to.

Also thinking about psychedelic experiences, where I heard about someone that got tremors automatically triggered in these states.
