thanks for your reply mrs D.

I have started taking 1000mcg sublingual tablets to check I don't have any reactions. If all is well after a few weeks, I will up my dose as you suggested.

It's hard to wait 30 mins to an hour to eat though! By that time I am starving.

Am I able to take my morning probiotics at the same time as the b12 or will this cause a negative effect?
