How should I supplement my diet with vitamin b12? - vitamin b12 and frequnt urinations

I am partly vegetarian. I eat only fish, meat or poultry. I do not eat dairy products. After a vote on the deficiencies in vitamin B12-address, I think it may have this problem. Before going to the doctor who can not pay, I would try to watch my diet with vitamin B12 to see if it helps. I do not want to overdose of vitamin B12 so, how should I do? What should I do with vitamin pills or ADITION to my diet?
