Haha ... yes, I should be out doing something, Jenny. I'm catching up with paperwork .......... and looking in on here :o)
I think the clarinet is a great idea. Not a huge amount of puff needed. Actually, saxes don't necessarily need that much. It all depends on the mouthpiece and reed set-up.
On tenor sax, I play with a huge big-bore mouthpiece and a fairly hard reed. You wouldn't need that. Certainly not on a clarinet. You can play as softly as you like.
Where you live, I would contact a local woodwind music shop. They will certainly know of the right teacher for you. The shop can also supply you with a student model clarinet. For example, here's a shop not too far from me. They supply their own brand of student model, as you can see from the link.........

See if there's someone similar near you. Some shops have a system where you can hire an instrument to see if you like it. Then, if you want to keep it, any payments you made will be deducted from the sale price, then you keep it as your own.
They will also know what mouthpiece/reed set-up you need to get you started. This kind of help is essential to get you going comfortably.
I hope that one of Answerbank's regulars, jomifl, will see this and join in. He's a clarinet player. I'm sure he'd be only too glad to help.
