Hey Kerri
I so remember those days and nights.............................Welcome to this site and so glad you have found us.
Yep you are dead right that it is definitely the Dex that is keeping you awake and I am with you in that I would have loved to have cleaned my house etc. but the fatigue and pain didn't allow me to do this.
I hope you have a great GP or chemo onco who is working with you to keep your pain under control. I think I was very much an exception to the rule with my pain though but I was suffering fibromyalgia prior to starting chemo so it didn't help.
There is no need for you to suffer with pain throughout your chemo and once chemo is finished the pain will decrease dramatically so it is not like you will become addicted etc.
I can relate and know where you are coming from. Have you got friends or family offering to help???? I am sure you have so if so put them to work cleaning, washing and ironing. They will be so grateful that they are able to help in some way. For me in the end I had to opt for getting assistance through Cancer Council as there wasn't family and friends available to support me. Cancer Council are amazing. Not sure where you live but in W.A. there is also Breast Cancer Care W.A. which is another fabulous service available.
I am wishing you all the very best and hope you manage to get some sleep and can reduce the pain. Talk to your chemo onc also about reducing the Dex so you can get more sleep.
Lots of love always, Mich xoxoxoxo
