I'm trying to increase my B12 level from 200 to 900. Can you tell me how many 500 mcg doses I should take? And what's the best schedule for taking them?

1 tablet daily for 3 months would help, because, orally only 10% of consumed dose will be actively available,the remaining will be excreted,hence it takes long time to restore,also consume eggs and adequate quantity of meat,they are rich in B12.

Question

I'm wondering about how long the protection lasts from tetanus toxoid shots. I never got the tetanus vaccination as a kid, but I did get 24 tetanus toxoid shots over two years, in 2016 and 2017. Is that level of vaccination enough to keep me protected, or should I consider getting another shot? Whats the typical duration of protection in cases like mine?

Question

I've been feeling really sick for about three weeks now, and it's getting frustrating. I used coartem and ciprotab during the first week, and while the body pains stopped, I'm still feeling super weak and feverish. It's hard to sleep, and every morning I wake up feeling terrible. I got tested for malaria and typhoid, and both came back negative. I tried paracetamol, and it helped a bit for a couple of days, but then I went back to feeling awful. I just can't figure out what's going on with my body, and I'm really worried. Any ideas on what could be happening?
