1. there are only 8 clubs that you can go to here, not your typical wild clubs...they are rather tamed and always asking for ID and membership when u want to enter.
2. alcohol is regulated, you can only buy one if you have a liquor license. you can get a drink only from hotels which i may say expensive.
3. you cannot kiss and make out in the car because once the police catch you....you are definitely saying goodbye to doha.
4. traffic is bad same like any other countries.
5. wear decent clothes all the time, shorts for girls are not normal here.
but if u are conservative guy, life in doha is for you. goodluck!
