I am currently on weekly self-injections which have been going well for a while. I am however two days late injecting this time and I am feeling terrible - I thought maybe I should give myself a double injection to try and get out of this situation asap.
Can I put two vials worth of b12 into one syringe and inject that? I can't think why not but I thought I'd check.
Thanks
(vial = 1ml, syringe = 2.5ml)
