Update
 

I was able to purchase ABC plus and Busy B from Holland and Barrett a few days ago. That's all we could afford right now but it's a start. I've been taking them in the morning so I'll just stick at it and hopefully it might help a bit.

Apologies for lowering the tone, but my word! Almost had heart failure until I googled and saw that riboflavin can have *ahem* interesting effects on the colour of one's urine. Should come with a warning label lol.

Thanks to everyone again for being so helpful.
