In the past year of so i have been suffering for some severe nausea and sickness , i only get it every few months but it lasts for days, Its almost like a viral tummy bug but without the throwing up. I know it may be related to my sluggish bowel movements, at the time i do not feel constipated but then i have a very large bowel movement SORRY. I know its related but how can i prevent this happening. I used to take a probiotic but not sure if it did any good. My diet is pretty good and i exercise daily. Any other suggestions. I am also 51 so the menapause is looming if this is at all related. Thanks for any help.
