Hi there,
I am not using the HTS now but I wanted to comment since my experience was a little different than everyone elses.
When I first started using HS I used a 3% solution. I coughed enough with that - for me it was enough anyway. When I changed docs last summer my new doc upped me to 7% and I had a really hard time. I ended up having to modify the dose to about 5%. The 5% was a good balance for me - it had me coughing plenty enough for me AND my doc and getting enough stuff up BUT it did not make me wheeze and get the tightness that the 7% did.
So IF you try the 7% and it is too much maybe you can just dilute it a little more to give a 5% solution. Just an idea.
Take Care,
Linds
