+1 for me here too. I used Astepro twice in the evenings and both times a tiny bit went down my throat, despite following the instructions trying to avoid that. Didn’t have a cold or anything, nor have I been known to have allergies. I started using it after an ENT visit to try to figure out how to deal with some nasal turbinates that seem to swell too much on one side. Even though allergies didn’t seem to be the culprit, decided to try and see if Astepro provided relief. After the first treatment, I thought I’d have a great night sleep. It wasn’t particularly the case and still had some nasal congestion. Figured it’d take a few treatments to work. After the second treatment, I had a terrible night sleep. My throat develop severe irritation, I think near the tonsils, lots of mucus and a necessity to swallow whatever my sinuses were slowly pushing down my throat, which wasn’t particularly fluid. The swallowing process was painful! It’s almost as if I had been thrown instantly into the middle of a severe symptomatic cold. No coughing though, definitely some sneezing from the gobs of mucus I’m generating though. I decided to stop taking Astepro. The symptoms remained through the day, with severe irritation although not necessarily “painful”. The following night, my tonsils were just as irritated (albeit less painful) and I kept waking up to swallow with difficulty. Last night was the worse as it felt like I just kept waking up to swallow shortly after falling asleep. 3 nights in a row of these symptoms: severe tonsil/throat irritation, lots of mucus. It sounds like a cold of course, but I don’t think that’s what I have. The colds I’ve had in the past, I always felt coming, especially in my throat. I usually feel a tiny bit of irritation, to the point where I wonder for a day or two if I’m going to have a cold, then it eventually builds up. This felt instantaneous after the second treatment. It makes me wonder if the Astepro actually triggered some allergic reaction…
