thanks for informations and advice, I appreciate it.
no, I do not have any option to try neuroptimal for a few sessions with a provider. I am from Europe and there are not any neuroptimal providers in my country neither in neighbourning countries. I can only take opportunity of renting neuroptimal for 30 days.
Anyway, I would rather try some professional trainers supervision first. Today I was calling with a EEG trainer from my area and i could possibly try 10-20 sessions with their eeg biofeedback in their centre (they also doing beginning diagnostic-assessment, that is probably essential as i read ). After initial training I may rent their equipment for a month with online support and consultation during that period. But on the other hand, i still do know nothing about their reputation and it is rather a private provider than specialized clinic in NFB field with psychologists and other staffs . I know they only use equipment from a czech company alien.cz with software - Brainfeedback2. It should look like as showen below:

... so I assume it wont be so powerful as for example TAGsync or neuroptimal system are (but i can be wrong about this). It will cost me only around 200 dollars for a month with unlimited number of sessions.
What do you think about this option? According to you, will it be waste of time ? I would rather invest my money (though a lot more) to something what is proven to work than something that "looks like" it could help and I have not found any review, feedback about it yet.
What is your opinion ? thanks.
