question: I started taking tres orix about 4 days now and notice that I am more lethargic and slow in energy. I must say that I was diagnosed with pancreatic head mass and lost close to 60 lbs over the last 6 months and have no apetite. I am trying to boost my apetite, as well as add some vitamins to my body. Could the tres orix be the cause of my lethargy? p.s. I have not started chemo therapy nor done any surgery.
