CHS is something that I have personally been dealing with since 2022 through several aggressive episodes and weeks of not eating.
During my last CHS episode I had not been hydrated well the day before so my body was already lacking water, this led to me eventually needing 2L of fluids from the ER. At the ER they gave me liquid Benadryl and Zofran in my IV, this helped keep my symptoms down until the IV fluids had all entered my bloodstream and then before being discharged I was given another dose of Zofran. When I left the ER I came home and had sips of water and some applesauce, I went to bed around 8:00pm and woke up at 1:00am with intense abdominal pain. After waking I took a Zofran to fight the nausea and got into a warm bath. I stayed in the bath for ~30 minutes and my nausea had subsided and I was able to fall asleep again. After waking at 5:00am with intense abdominal pain I then puked until there was absolutely nothing left and I was dry heaving. At this point I took a suppository Promethazine to help with the nausea, I got into the bath for 30-45 minutes. This was the last aggressive vomiting session I have and I want you all to know that I understand what CHS feels like directly through multiple episodes and that I will do my best to create a valuable resource here that can help people suffering from Cannabinoid hyperemesis syndrome.
