Hey sweety
I am glad you made it through your day and it wasn't as traumatic as you thought. I have recently been dealing with nausea for a different reason than yours and I can also remember the lovely nausea from chemo.
Things to try are peppermint tea that you are already on to. Ginger anything even biscuits with ginger in, my saviour has been Mylanta chewable tablets or 2mls apple cider vinegar from health food shops in a small glass of water 1/2 hour before eating seemed to help as well.
Don't elevate yourself using a pillow but if you feel you need to be elevated then bricks under the head of the pillow. I found a heat pack in the upper abdomen region when trying to sleep was a comfort as well.
I fell in love with relaxing comforting baths before bed during chemo so maybe give that a go.
Continue with the fluids. Use the Dex only as instructed as it will keep you awake and too much can make you anxious but it is amazing for nausea. Zofran is another drug your GP/oncologist can prescribe which is expensive but very effective.
You may need a port fitted if they have major problems with setting up the chemo. Might be something worth mentioning at your next appt.
It is very understandable that you are emotional and certain things and certain scenes will set it off for you. It is very very normal. We are human at the end of the day and riding on a very emotional rollercoaster ride.
Accept your feelings, cry if you need to cause crying is very healing to the body. Congratulate yourself on making it through the day and keep on making them fellas loving the look darl lol hee hee. Keep that beautiful smile of yours happenin.
Nurture yourself, accept the help,love and support that will come your way and forget about us females having to be superwomen for a while.
Wishing you wellness and remember day by day my luvly.
Take care, lots of love,Mich xoxoxox
