I guess it depends on how long you go between your shots, and what your b12 levels are.. but I googled B12 deficiency symptoms and got this: 

Symptoms of vitamin B12 deficiency include very pale skin, shortness of breath, fatigue, dizziness, headache cold hands and feet, heart palpitations, and chest pain. These symptoms are due to a decreased production of red blood cells that are necessary to carry vital oxygen to the body's cells and tissues. A serious complication that can occur due to decreased red blood cell production is pernicious anemia, also called vitamin B12 deficiency anemia.

Vitamin B12 deficiency and vitamin B12 deficiency anemia can also affect the gastrointestinal tract and result in enlarged liver (hepatomegaly), nausea, vomiting, heartburn, abdominal bloating, gas, constipation or diarrhea, loss of appetite, and weight loss.

Symptoms can also occur in the nervous system. If left untreated, vitamin B12 deficiency can result in permanent nerve damage. Symptoms can include numbness and tingling in the hands and feet, unsteadiness, difficulty walking, confusion, depression, memory loss, and dementia....

I take a B Complex with 2000iu of B12 along with a 1000iu B12 sublingual a day.  My range is up near the 2000's....
