I've used EFT and even more so, TAT, extensively while listening to Holosync. A nice variety is the "slow" tap
that Silvia Hartmann came up with.
I find that by tapping/tat'ing ahead of the HS session, or when stuff comes up, it can really cut down on overwhelm.
Using TAT, I frequently use "it is not safe and not OK for the energy to flow" followed by the opposite statement,
and stuff flows and clears really smoothly.

While on AL2 I had some sort of kundalini episode that lasted for some weeks. Dunno if I had survived without EFT!!
HS is simply fantastic, but I feel sorry for those doing HS without having the resource of EFT or TAT.
LOL!
