EMDR - has anyone tried it and found it helpful

Hello everyone,

I’m considering trying to access EMDR to help me deal with a traumatic experience/PTSD. 
Has anyone tried EMDR - what was it like and did you find it helpful? 

i can’t seem to get any therapy on the NHS (at least not without waiting for over a year) - I can’t really afford to pay privately but might have to as I really need help. I don’t want to waste what little money I have on EMDR if it’s not likely to help. 

has anyone had a good experience with EMDR? 
thanks
