2 months is hardly enough time to really find out if the job is good or not, it is not a good thing to job hop all around but if you can't stand it then you quit if you can afford not to have this money to buy food
Always be on the lookout for new opportunities, but do not use your time at work to actively seek employment, as you will be doing this on your current employer's payroll. If you have references from previous jobs, get in touch with them and let them know your situation. If you don't currently have references, talk to your current employers and let them know in the nicest way possible that you're not happy and would like to move on. They may be interested to know what the problem is and work something out for you. It really depends what is wrong with your employer exactly.
Behave professionally and do not burn down any bridges.
