I am about to start my 9th cycle of Eribulin. I lost about 3 quarters of my hair. I have my infusion(which is a 5min push) on Monday, I feel slightly bone achey that night but panadol osteo helps with that. Wednesday my mouth gets a bit yucky with blood blisters and ulcers but they resolve quickly. Thursday,Friday and Saturday feel a little more weary but its manageable. Second week is slightly worse than the first. I do have some minor neuropathy but Onc said unless my balance is affected no change tp treatment. I have been neutropenic lately but no infections. All in all its a fairly cruisy treatment. I am a single mum of 11 kids and still manage to deal easily with day to day living. There is a small Eribulin/Halaven group on breastcancer.org and we all keep rach other updated. Good luck
