Tonight is the second time in a week that I got light headed and threw up yellow bile. I also have been experiencing headaches everyday for about a week (I wake up with one). I take 2 Ibuprofen and it goes away. I do not have a gallbladder (removed in 1989). It is almost like flu symptoms but not everyday. My daily medicines are Pravastatin - 40 mg., Losartan - 50 mg., Hydrochloroth 12.5 mg., Aspirin - 81 mg., Multi-Vitamin,(all 1 daily) and Tramadol - 50 mg. (as needed - I have Fibromyalgia (1 in morning & 1 at night). I am 66 years old (retired) and I am always tired and have to force myself to do things. I do not let my condition stop me from doing my own work - I pace myself. Should I contact my doctor or wait and see if it happens again. I very seldom get headaches so I am concerned. A friend told me not to take Ibuprofen. Thank you and will be waiting for your reply.Cynthia Chase
