Hey, I posted my first thread a couple weeks ago when I got my 1st shot and just wanted to say I got my 2nd. I immediately felt better but that went away after a few hours. I've been taking folate but I still feel extremely tired so I started to eat a lot of oranges just in case it has something to do with my potassium. My doctor said it should be fine to take 1000mg b12 supplements but I'm not entirely sure. She said that I should feel better if I start eating kale and other things instead of taking the supplements but if that's the case I'm not quite sure she knows where b12 comes from, or if she even believes I have PA. I messed up my sleep cycle a couple nights after I got my first shot. I developed insomnia and found it extremely difficult to fall asleep, and now I've been sleeping in the daytime. Any advice?
