I had a good time with holosync to begin with but found it caused a lot of upheaval especially when moving to new levels. I had a huge overwhelm incident when moving from Awakening Level 4 to Purification Level 1 and it took me over 18 months to overcome it (anti-anxiety and antidepressant meds needed!!).

Be careful with holosync, I don't think it's safe really at all.
