Hi ron tucker, I went thru what you are going thru 4 years ago in 2020. It was very hard on my wife. Your wife is probably fearful and does not know where to turn. My Christian faith during that time was priceless. Chemo would get me all hopped up with the steroid they put in the mixture and I would literally walk for miles to get tired enough to go to sleep. THC of the indica family is great for sleep, but some edibles are so weak you might as well take an aspirin. Try eating a little more than what they tell you and Indica is what you want.I also take one 10mg valium 1/2 hour before bed. Exercis daily if you are able. Activity helps get your mind off of your ec. You will get better but it takes longer than what you might think. It took me a good 2 years to adapt and eat right and I still blow it periodically. Try not to eat anything for 2 or 3 hours before bed so there is nothing in your stomach. I finally reached my pre-surgery weight and I am stronger and fitter than I was at age 45. I am 70 now. Hopefully, you will be, too. Cheers and prayers being sent your way for a successful recovery. (The pic I sent was taken today. We bought 2 Widescapes to make us get outside more.). There really is life after cancer.

I have traveled this road also. Look into Magnesium supplementation as it can be low and interfere with sleep. I found some relief with a supplement that is made into a drink or a tea from the Nuun product line. Nuunlife.com and the product is called Rest. I also use an essential oil diffuser with lavender beside the bed. There are lavender sprays that also help. I am lucky that taking 2 Tylenol at bedtime helps my stay asleep also. Using several things at once is more likely to help you than just trying one at a time. I also use 2 MG of Melatonin occasionally. More is not better with Melatonin. Good luck on this issue. Getting 4 hours of uninterrupted sleep is such a luxury.
