Chemo really does create havoc - just dreadful.Have had 3 ops in the past 5 weeks and must be lucky as my blood pressure is still excellent and have been on high dose Vitamin d nearly a decade because of osteoporosis.But my formerly good cholesterol more than doubled after starting Letrozole- am hoping Krill and low dose aspirin will help as refuse to back on statins because of side effects . Guess we can only try things and see what works for us.
