JamesD, overall this sounds like a good report at 10 weeks. I'll try to answer your question to the best of my knowledge.

The weight loss. Is this after you went back to work or did you work all along? Are you being weighed on the same scale, preferably in the morning, and with the same articles of clothing, preferably without. Your weight can vary by 5lbs throughout the day. Different scales, who knows. Even at my doctors, I sometimes see two, and my weight differs by several pounds. Are you measuring your intake? You may not be eating as much as you think, plus working will burn extra calories.

Fatigue could relate to your food, water intake, lack of sleep, medications, recovering from treatment, could have low blood counts, hemaglobin. TSH, testosterone, B12, Creatinine levels, so these should be checked by blood work. A CBC doesn't test all of these. There is something called CIF, Chemo Induced Fatigue, most of which is not fully understood, but basically says to take care of what you can that is deficient, such as items I mentioned.

Dry mouth overnight. One thing is the salivary glands basically shut down at night, and why people wake up with morning breath due to the build-up of bacteria, plus the majority of moisture is lost when people sleep with thier mouth open. There are products out there to help keep the mouth closed. I've seen one used for snoring or use tape, but check that out with your dr lol. Another is to sleep with a humidifier, drink a glass of water before sleeping, and keep a bottle reachable during the night. I heard some using a camel back, which is a water pouch, used with biking to sip water from, but I never did that. I used biotene dry mouth gel on my lips, inside mouth before sleeping, and that seemed to help some. Some Medications can cause dry mouth too, but if you need them what can you do, except maybe altering the timing schedule if you can. Water only hydrates the mouth between 12-16 minutes. Others like milk last longer, replicates saliva. Maybe others like coconut water, lemon water since citric acid helps produce saliva.

Keep up the good work.
