Hello and welcome,
I'm just going to answer the first question you pose.
The easiest way of holding the tongue and which seems to me to be the most natural, is to think where you place your tongue when you say the letter L. You find that your tongue sits gently on the roof of your mouth just above the teeth. I have no problems holding my tongue there and it doesn't restrict breathing etc.
and you can still swallow without breaking the contact.
I too had a great many pain issues and found that SFQ got rid of all my pains, arthritis, trigeminal neuralgia,included. However I would say that to completely get rid of ALL pain took about 8 months but as I had pain for 10+ years I am delighted and would recommend SFQ to anyone. Just persevere and be positive.
Hope this helps,
Love & light
Faune
