Kesimpta intensive start

I’m loving from brabio to Kesimta. I’ve been stable on brabio for years with next to no side effects, but it’s failed and my only options were Kesimpta with intense start or Lemtrada. I’ll be isolating and taking a high dose of Kesimpta for three weeks, then moving to the normal monthly jabs. Anyone experienced this or another intense start med with immune system risks and how did you find it?
