Your dd sounds lovely treedeliver.
I found Ortisan very effective too. And it doesn't taste that bad really.
I'm going to try to summarise the yoga stretch I find best as follows:
NB - as with all yoga it is all about the breathing!
Lie on your back with your arms by your sides (hands flat on the ground, pointing to your feet).
Exhale until totally totally empty - feeling your breath leave the top of your thorax, your chest and your stomach. Hold it until gasping.
Breathe in very slowly, filling your stomach, your chest and then thorax until you are full of breath. At the same time move your arms slowly in an arc above your body (keeping them straight) until they are above your head and you are lying in a flat long line . Stretch as much as you can (focus on the abdomen).
Repeat this say 3 times.
Then
Repeat this but switching the breathing round so that when your arms are above your head and you are stretching as much as possible you have exhaled and so are empty of breath.
(and vice versa, so inhale when you lower your hands to your sides to be pointing your feet and exhale as you raise them to above your head)
Your stomach and abdoment will be very flat at the point where you are stretched and have exhaled and so sometimes the massage can help at that point.
Repeat this exercise approx 5 times (although my instructor used to say any more than 3 time would result in a bowel explosion!! - certainly never in my case!!)
The exercise would be best done in conjunction with the whole yoga practice as I think the relaxation of the whole class plays an enormous part.
