I had the hot flushes too from chemo I would sleep on a towel some nights and have a squirty bottle by my bed. I finished chemo oct 16 then in July 17 almost overnight they all just stopped along with the residual neuropathy in my hands. Just got lucky too I guess. I’ve seen those cooling mats in the tv direct shops I would of tried them if it was still an issue. Mind you I was triple neg too so I haven’t had to take any post chemo meds. So maybe that’s helped.... I don’t know. Big hug. Margie. Xx
