My Israeli landlord complained strongly, and told them to move it (there are some real advantages to renting…) My husband went down a couple of days' later, to politely request them to move the aircon (as a Brit, he was clearly completely ineffective. See my earlier comment about the Israeli landlord).
Downstairs told him: 'We've called the technician. It's being taken care of.'
Five days after that, my nervous system effectively packed up, and I started to get all sorts of weird physical symptoms, including feeling like I was going to throw up, a weird buzzing sensation throughout my body, an inability to focus my eyes, and strange pains all over my body.
And I had no idea what was causing it.
In the middle of all this, the downstairs neighbours came up to ask for my landlord's phone number. "Is it just him, or you that's got the problem?" she asked me. I told her it was both of us: it's his flat, but it's our quality of life that's being ruined by the non-stop noise her aircon was making.
She wasn’t impressed. "I've got small kids and I don't want them going near the air-conditioning," she told me. "Even if I move it, I'm only moving it a little bit."
In the meantime, the unit didn't go anywhere, and my nervous system crashed. It took me a day, and my daughter doing the very easy pulse test on me (which you can learn as part of the new JEMI certification course - more about that another time) to find out that the main problems appeared to be bladder, Triple Warmer and large intestine meridian.
Bladder is nervous system - and it was completely shot. As I was lying in bed asking G-d for a clue as to why that had happened (and feeling dizzy, nauseous and otherwise physically-wrecked) - downstair's airconditioning whirred on again - and I suddenly felt like I couldn't take another second more.
In my room, you can't even really hear the noise (although it's deafening where my kids sleep) - but there was an almost imperceptible 'hum' and vibration. My walls were shaking, and the barely audible 'buzz' felt like it was all around me, somehow ripping my nervous system to shreds.
I opened the window - louder noise, much lesser vibration - and felt much better, but still pretty awful.
What was I going to do about this problem? And was it REALLY their aircon that was causing so much damage to my health?
Then, it started snowing and my neighbours left for two days, and for the first time in a week, there was no aircon. I got my answer super-fast: yes, their air-conditioning was most, if not all of the problem.
I woke up today feeling so much better. In the meantime, as well as holding my bladder strengthening points, to try and help my nervous system pull itself back together, I also started praying my socks off, because now I have a big problem:
My neighbours clearly love their aircon. Just as clearly, they don't really care what impact it's having on me, or my health. I'm in this flat for at least another 9 months - and I can't cope with non-stop vibrating aircon for that long.
The week I've already experienced nearly killed me.
It seems like an unsolvable problem, even when you have an Israeli landlord to go and do the shouting for you.
So I'm praying, and hoping G-d shows me a solution that won't lead to any more sinat chinam, or brogus, G-d forbid, but won't make me crack up, either. It's a tall order! But G-d can do anything.
