Mom is in her 3rd chemo treatment today. 3rd of 6 total. While technically "halfway" will be 10 days from now, as far as treatments go this is the middle.
She's been able to hang in there. Tomorrow she'll be ok, Thursday she'll start feeling rough and will be out of commission on Friday and possibly the weekend. Then after that, she's ok until the next treatment with only the standard issues normally associated with chemotherapy.
But, at least it is, for the most part, halfway over.
