Hi,
I have the same problem .. very high cholesterol within three months since I started using Arimides (and I never had a cholesterol problem before). I just had my first check-up - mammo, bone density, abdominal x-rays etc the latter which reflected gallstones, this being caused by the cholesterol. I am consulting with my surgeon this morning - the oncologyst has recommended that the gallbladder be removed! ... more surgery within six months of the lympectomy.
Apparently all this kind of medication, i.e. Tamoxifin and others can cause high cholesterol.
