Hi,
I didn't "feel well" before treatment I had some kind of cold with post nasal nastiness, and they still let me treat and I was in a study,,, that was my only feeling unwell and it seemed to last a long time into the treatment.. or who knows I could have had symptoms from both,, but I still treated,,, "Thank Goodness......

So just to support what Hector said since this is a repeat post. When people don't feel very good before they start treatment , the liklihood of them dropping out due to side effects increases. When they drop out after dosing, they create resistance (think TB superbugs from not going the dstance with the meds) and may not be able to treat after that.
"Feeling unwell" can mean many different things. Are you emotionally depressed, physically exhausted, having discomfort or pain, or all of the above. A full physical and psychological examination should be done prior to treatment to identify any issues and concerns.
