I don't know what I'm expecting..Just need to write about it I guess hoping that if I do things will get better again. I had been doing quite fine of late. Not because I habituated , but because the noise calmed down a bit. Everything is in its level. I managed to be happy again no matter I had T, but as I said, only because it was bearable and because I had silent quite silent mornings most of the times and if I didn't hear it outside , I was already happy. However, I'm experiencing a spike now..It's been four days. My T has always been mostly a hissing kind a bit all over the head. If before I felt like I had a thousand of tiny explosions in the brain per second, now it feel like twice more of them and sometimes I simply find it unbearable. The thing is I took a plane 6 days ago. It was the 4th time since my T, 2 h 15 min flight and all the time either with earplanes or with earplugs. I'm pretty sure I didn't experience any barotrauma, I 'd notice sth I guess. I popped two NAC on the day of the journey and one morning after. I had a spike right after the flight and until the end of that day but I didn't worry since I was mostly extremely tired after a few short nights during holidays. And indeed, after a good night sleep T seemed ok. One more morning and day without changes but I guees it was on Thursday evening I noticed sth 's different and that hasn't changed since. I'm once more deeply depressed . I'd tried not to panic and just wait but today, 4th day on I feel like I lost control over my life again. I 'm only waiting for the days to finish to be able to go to sleep and hoping to wake up with almost silence again. Before any worsening didn't last more than one, two days maximum. Good sleep doesn't help, nor does magnesium, melissa, hydroxizine that I take once every 3 days in a tiny dose, but I felt like it helped too. Now all this doesn't seem to have any influence. God thanks I can sleep fine and I'd say it calms down significantly after I have laid for a while. But very often I just don't want to wake up and start the day if I notice that already in the morning I hear this hiss quite loud in bedroom. I try to tell myself that this shall pass too, but until it does I'm tormented by the thought that maybe it won't .. and I can't live like this. I mean I can survive, but not enjoy life or project things in the future..Do you think a flight could cause it ? If so, how long does it take for the post flight spike to settle ?
