While your waiting for a B12 shot, you might try taking some sublingually with sorbitol. The latter allows most (but not all) people who have absorption problems to get enough. http://ajplegacy.physiology.org/cgi/content/abstract/193/3/513 http://ajplegacy.physiology.org/cgi/content/abstract/193/3/5...
