I had 6 rounds of Docetaxel back in 2019. As others have said above, it certainly isn't as bad as some chemotherapy drugs, and there are some 'hacks' that make it easier to tolerate.
The hacks I found really effective were:
-- take a vitamin B supplement that has high doses of B6, B12 etc throughout the treatment. This helps to prevent nerve damage and peripheral neuropathy (tingling, numbness and loss of feeling in hands and feet)
-- suck ice cubes or frozen fruit cubes during the chemo infusion, helps to prevent loss of taste buds and lessens 'metallic mouth'
-- when self-injecting the GCSF before each infusion, take the antihistamine loratadine. I had terrible bone pain from the GCSF injections, because they basically send white blood cell production in your bone marrow into overdrive. The loratadine took away the pain completely.
I know just the word 'chemotherapy' sounds scary and conjures up all sorts of nasty images. But Docetaxel really isn't that bad. After the first cycle, it's entirely predictable: you feel great for 3 days because of the high dose of steroids, then you'll crash off the steroids and feel like you've got 'flu for 4 to 5 days, then you'll recover and have 10 to 12 days of feeling fine, then it's time for the next infusion. But with the hacks I've mentioned, and keeping active, it's totally manageable.
