I've not had acupuncture before but I do hold a very high opinion of it going by other people's experiences. I have had shiatsu, twice, and the results were amazing. I had both sessions in late pregnancy when anxiety became too much to cope with and I had to be extra careful with medication. I went in the first time a complete wreck, I was utterly miserable and felt constantly on the verge of a panic attack every waking moment of every day. When I came out, I had the biggest smile on my face I'd ever had and I felt no anxiety at all. It felt as if it all just melted away and I was so peaceful. It lasted a few weeks without more sessions. Sadly, I couldn't afford to go back because we had to move house so we were broke.
Now that I'm not pregnant I would love to give acupuncture a go!
