Look, I’m not an expert so take this comment with a grain of salt, but in my understanding vitamins and minerals are stored slowly in the body. There is a limit as to how much you can absorb of anything at one time. Taking two tablets now is probably wasting good part if not all of the second tablet. If your deficiency could be solved faster by taking larger doses your doctor would have already recommended that one for you.

I’d be thinking ways of making sure I remember: set up reminders, keep my pills in two or three places so I can access them immediately, trying to make a routine out of it (it’s hard I know), keeping track of it in a journal.
