Yes, I've done both - started EFT in July 2006, TAT later on in the winter.
I found them both useful, and for same or different things.
The feeling after TAT is more mellow, while EFT is quite energizing mostly.
Yes, some of my deep seated things 'melted' too!
In addition to this, I found journalling and de-negativizing (as suggested in 'The Feeling Good Handbook' by Dr David Burns - basic cognitive behavioural therapy;)), affirmations (also used in later rounds of EFT), and writing down wishes & obstacles (as shown by Barbara Sher) very helpful, and all fits together nicely. (I've done all these before and continue to do them.)
There were times when either of them wasn't what I needed and my system just needed some sleep, for example. Or to let out some excessive energy (as Don Greene shows in his book, or by running etc - hope that makes sense?).
Just wondering, do your hands get very warm when you do TAT too?
Mine did, while eg my Granny couldn't do anything when she did it to herself. I could talk her to sleep with TAT, but she couldn't talk herself to sleep using it. (I am familiar with books of Barbara Brennan and read a book on reiki too, so this may be something to do with that. Have you read any of these books? Tapas mentions B.Brennan in her credits, I think.)
Anyway, so excited to find someone who does TAT too!!
Love,
Andreya
