I just started Vyloy, I have 3 esophagus cancer , anyone else on this

I have non operable stage 3 possibly 4 esophagus cancer, I had 9 round of Folfox with adding Keytruda. I actually thought I was doing well my tumor shrunk to the point I can eat like a normal person and actualy put on weight. The cancer facility I am being treated at was excited that I matched the Bio-markers for Vyloy and had my first treatment last week my 10th overall treatment. For me it hit me hard I pretty much slept for 3 days and the last 4 Ive really not felt myself, lack of energy some dizzyness. I had been one of the lucky patients not really suffering with my prior treatment with the Keytruda and Folfox. My question is does the after affects wean with acclimation or is this what my future looks like as I am more concerned about quality of life not an extension of poor quality. To my knolwedge my treatment center only has one other patient on this simular treatment so I havent found others to discuss their reactions.
