Oh no that’s awful. my husband had that and he was so ill. I had to take him to hospital to be put on a drip to rehydrate him and have anti sickness drugs and bring his temperature down. He hadn’t been able to keep anything down or sleep for days. Hope it doesn’t get that bad for you, if you’re not improving get someone to take you to a walk in centre, they can help you much better than you can help yourself at home. Hope you’re feeling better soon xx
