Had my first infusion 6 days ago, felt fine after, next day enjoyed a spa day, but by the end of that day, headache, Fever and bone pain, stayed in bed the next day, then back to normal. Although on the eve of day 5 experienced sickness and diarrhoea, sweats and chills. I'm not sure if this was due to the drug or something I'd eaten, but I'm not generally a person who suffers that type of thing. Would like to hear if anybody else has experienced this after a few days.
