Recommendations for recovery regimen following folfox

After two years on folfiri, and one on capecitabin, my cea numbers started to climb into the 30’s. I’ve now switched to folfox and after three treatments my numbers have finally started to drop. 🤞. I thought Folfiri was bad but the Folfox is pretty bad too. I get infused for three days but it takes 2-3 more before I start to feel human again. Is there some trick to shortening the recovery time?
