I woke up last night around 3 AM and suddenly couldn't breathe properly. It really scared me because it was the first time it happened, though it eased up a little afterward. I'm wondering if I can take medicine like Deriphyllin to help with this?

It sounds like you're experiencing sudden difficulty breathing, which could be due to several factors. While Deriphyllin can help with breathing issues, it's important to consult with a doctor to determine the underlying cause and get a proper diagnosis. If the symptoms persist or worsen, please seek medical attention as soon as possible.
