Hi, I Have Breast Cancer Stage 4 With Metas To

Hi, i have breast cancer stage 4 with metas to lungs. Lately, result of my sgpt was high. My doctor prescribed godex sd 3x a day. What are the side effects if i take this with other meds like femara and supplements? Also, I am drinking some herbals, will this affect my treatment for fatty liver? I feel weak and nauseous. Is this a normal side effect? Thanks for your help.
