Please can someone help??

I finished chemo for breast cancer 6 weeks ago and started radiotherapy 2 weeks ago.

My absolute

JOY at finishing chemo has been seriously marred by RIDICULOUS hot sweats.

I don't mean menopausal hot sweats - I've had them.

I am literally SOAKED  every 20 minutes or so. which means I'm constantly damp. then I'm freezing. All day and all night. I can't wear nice thing and i have to wear leggings in warm weather otherwise i look like ive wet myself - sweat drips down my legs.

I've been taking primrose oils - drinking my bodyweight in water - eat LOADS of fruit and veg.

PLEASE HELP!!!
