I am a 51 yr old male I have not eaten properly in 20 yrs, burgers, fries, sodas, my body eventually about three weeks ago said stop. But my appetite since has dwindled and keeps dwindling, I have hot flushes, diarhea, excessive urination and gagging. Yes I am a smoker. As well as marijuana (medical). I also feel a bit depressed I was taken Xanax for anxiety and nervousness . I was diagnosed with IBS years ago. Should I go to the ER as my Doctor will not be in his office this week.
