For the past few days I have been feeling quite sick, (as in nausea) and I kept eating though as they felt like hunger pains, afterwards though I would feel the pains and get a rush of nausea but then it would eventually die down, I had also what I thought was some constipation where my 'deposits' would be rather large but later on they just got easier and turned into what I thought was diarrhea! I have had a crazy appetite during the past few days... last night I felt rather unwell but I just went to bed and during the night I kept feeling sick but I just slept through it, until this morning I felt quite hungry but sick at the same time so I went into the fridge and took a quick drink of milk. I then had diarrhea afterwards and then once again, very severe (without going into details.) I have been feeling sicky and I don't know what to do, I don't know if I should go to my doctor or if it's too mild or not. I live in the UK so I'm not bothered about seeing a doctor (like some of the questions on here from US residents.)
