I wanted to try this, but in the US it is considered experimental for sz. You can still get it some places, (as part of a study) but I didn’t qualify. However I did find out about side effects, and you usually get a weird tapping sensation they describe as fingers tapping on your head during the treatment, sometimes a feeling of warmth on your scalp, and headaches which typically go away with a headache medicine, but in any case are short term. There is a very, very small risk of seizure, but remember there’s a very small risk of seizures from going to the fun house and seeing the strobe light. Also some people report temporary agitation and transient insomnia.
No one has ever reported having their brain turned to porridge
