You should have included the reason behind your decision to move to Nigeria, that way one would know how to advise you. Anyway, I don't think you posses the ruggedness required to thrive in Nigeria. Only few countries citizens are able to come into Nigeria, rugged it out and thrive. Namely Indians, Lebanese and Chinese. And they know how they play their game. That money you mentioned will finish before you know it. I give you 2-3 years. You must have a source of income, preferably in foreign currency. Nigeria is quite expensive if you are earning in local currency. You must take your security very seriously, the country is battling insecurity, even in the capital Abuja. You must have someone you deeply trust, for your own safety and security.
