Ive been upping water, and electrolyte drinks...feeling better. Thanks for suggestion Sheldor and Sally MatildaNo its not normal. You are the first person I hear that feels sick.
Check that you drink enough. you need to drink on Tire more as usual.
Take electrolytes on the day of injections.
Take daily B12 and Magnesium and Multivitamin
I've been taking vitamin b for two years now. From what I understand, when taking B12 supplements, try to avoid drinking coffee or tea at the same time as they may interfere with the absorption of the vitamin.I concur with Sheldor about the water, electrolytes, and vitamins. I'm currently on sema and do have some nausea occasionally. I regularly take vitamins (especially B12, as I eat a vegan diet), but sometimes it's hard to get enough water in. I think that is usually the cause of my nausea, and my doctor agrees.
