Does anyone know a good multivitamin to help fight fatigue? One that really works and gives you energy? I know vitamin D is supposed to help, is there anything else? This fatigue has got to go. Update: I have been on the vitamin for four days and I haven’t seen any changes, I know it’s probably going to take longer, but I just had IVIG infusions in the hospital for 5 days, just got out Monday. I figured by now I would start to feel some changes but still nothing. I’m still so drained and anytime I do anything simple (pick up toys, do dishes, walk up the stairs, laundry, etc.) I get completely exhausted. Hopefully I’ll start to see something pretty soon. Also can I start Kesimpta while I’m still feeling this way?
