Meprobromate is not an alcohol, but a carbamate.Carbamates are made from a parent alcohol. It is like an ester but has a nitrogen (amide) linkage opposite the oxygen that would be the ester bond.

There is a carbamate form of ethanol called ethyl carbamate. It actually is a stronger sedative than ethanol, but is a fairly nasty carcinogen so is not used (even worse than ethanol itself).

A lot of old sedatives were carbamates, and usually the corresponding alcohol is a sedative too. However carbamates can have other functions, a lot of pesticides are carbamates, and inhibit the enzyme acetylcholinesterase like nerve gas does.
Alcohol just means a compound has a free hydroxyl (OH) group on it. Alcohols are only liquid when low molecular weights. Alcohols can be solid or liquid (adding an alcohol group actually raises the boiling and melting points of compounds. Methane is a gas at room temperature, methanol is a liquid. Same with ethane and ethanol, propane and propanol, and butane and butanol).
Just because something is an alcohol does not mean it will get you drunk.
