Additional information: The patient did not take any other vaccine in four weeks prior COVID -19 vaccine. She was not diagnosed with COVID prior vaccination and tested negative with COVID post vaccination on 12Apr2022 iHealth Antigen, nasal swab test. The patient had no known allergies. Starting a day or two after booster shot, I woke up every day feeling hungover, despite not having had any alcohol. I had pounding headaches, general GI distress, disturbed sleep, and significant fatigue. Those initial, more severe effects, faded somewhat after 1 week. But I still have ongoing GI issues which are significantly impacting daily life. I'm still having disturbed sleep as well, though I'm unsure if that's simply a secondary effect caused by the GI issues. The GI issues are: lots of heartburn/reflux (something I don't normally experience), bloating, morning diarrhea. I'll often wake up between 3-5am, unable to fall back asleep, with my stomach gurgling. The sleep I do manage to get doesn't feel "restful" and most days I feel pretty fatigued as a result.
