In my case after my covid in may 2023 i have difficulty falling sleep naturally. My doctor recommended i try zzquil with melatonin and lavender and chamomile. Recommended dose is 2mg but i noticed if over 1mg my head feels heavy in morning. With 0.5mg zzquil and 1 benadryl i can sleep. But i want to get off benadryl as it has so many side effects. Any suggestions on what i should do. I am trying to get an appointment with sleep clinic but appointments take long time to get.
