still tired after vitamin b12 injections I Feel All the Time. Do I Need a Shot?: Shawn Veiseh, M.D.: Family Medicine tired after b12 injection vitamin
Description
B12 shot benefits include increased energy, support for healthy nervous system function, and a boost in red blood cell formation

The ERCP can aid in diagnosing problems in the bile duct and pancreatic duct and in making repairs
However, there are some groups of people that may be at a greater risk of vitamin B12 overdose

Scared it will do more damage I am concerned with statements like these solicited adverse events were generally short-lived. Pfizers report has similar language (most resolved within 2-3 days)
