Does anyone have any calming techniques?

I have awful anxiety, with panick attacks associated with panic disorder. I have had thus since I was a child of 6 or 7. I am prescribed a medication to get rid of the anxious feeling I have when I feel a panic attack coming on, but I hate taking pills especially the ones I am supposed to take for this disorder, for they are highly addictive and bad for you all around. So, when I feel as ifs panic attack is coming on does anyone have any helpful ways to get rid of the attack with out use of medication? Ive tried many things and nothing seems to work!
