Advice on how to prepare for TC chemo?

Hello everyone! First time of me starting a thread on here, hoping to get some advice from someone who’s had experience going through TC (Doxetaxel & Cyclophosphamide) chemo recently? 
I’ve just had a mastectomy with an implant reconstruction on my left breast after I had a recurrence after going through lumpectomy followed by radiation in 2024. It’s been very traumatic to say the least!

Now I’m really freaking out about having to go through chemo as I’ve already been swapped to letrozole and Zoladex instead of tamoxifen which I was on before and I’m already having loads of hot flushes etc so adding other side effects on top of that feels very daunting!

If anyone have any advice how to manage side effects that would be amazing! I’d love to at least attempt to not lose all my hair and eyelashes, eyebrows and maybe there’s some supplements I could take to make sure my skin doesn’t get too damaged during treatment? I’m going to bring in ice cubes/lollies to suck on as I’m having the treatment done but wondering also if there’s anything else I should be doing or bringing with me to the appointment?

Thank you so much!
