I had one of the worse nights ever with T last night. It screamed and stopped me sleeping. I finally gave in at 3am and got up. My reaction to it these days is different from the beginning - I still hate it but there's a kind of 'acceptance' so I tend not to panic too much. But last night it was as loud as at the start & it is SO annoying at that level. From 3am until 6am it still screamed. At 6am I opened the windows and the back door - no noise outside... same noises inside (Jim's water sounds - thanks Jim.. wish you were still posting!) as always. And bang - the T volume dropped down to a tiny tinkle. It was so sudden that it scared me. I know that we don't all have 'variable' T but many do as they have said that they have good days & bad days or that it gets worse in the evenings or screams in the mornings. The fact that mine has varied so much since the start just serves to confuse me and I've had long periods when it's gone altogether (however much I listen to it.. and I can't help but listen!). I've given up searching frantically for a cure (I do it more leisurely now ) but I can't help but think that eliminating or changing something may get it down to a permanently quiet level or get rid of it altogether. With this in mind, for those of us who have variable T, could you post what you think affects it or caused it in the first instance please? I'll start by saying: Main cause suspects: 3 weeks of sleeping in silence or 2 rubs of ibuprofen (topical application on knee) or an allergy of some kind to something in my new environment or air pressure change (after living for 3 weeks at a higher altitude with higher humidity in Cornwall) or two 7 day courses of doxycyclin 4 & 5 months before onset. Main loudness/spiking trigger suspects: bending neck forward or sleeping without neck support, MSG in chinese sauces (only tried it once!), weather fluctuations - air pressure/barometric pressure, humidity, increase in dust in air (discovered when I put the central heating on), computer screens / CPU, superhub router / modem. I'm not sure about any of these - as someone else said 'it's the blind leading the blind' and there are just so many variables that it's hard to conclude anything - especially with screaming or buzzing in your head but I'd really like a list from as many people as possible so that I can review my own and try to eliminate or discover possible causes /triggers. Thanks!
