Hi @jillco. Think you may find many under the post covid group who experience this situation with some formally diagnosed with mast cell activation and many others maneuvering their healthcare systems seeking help/diagnosis. My providers explain that our bodies are basically fighting themselves, central nervous system disruption causing sleep and central apnea, newly highly reactive, and new histamine food/drink intolerance that releases about 3am each night🙃. Hope this direction helps you find your answers and quickest healing to you🌈
