Taking sleeping pills with drinking alcohol will increase the affects of the sleeping pills?

Yes: Combining any sedating medications (including sleeping pills) together or with alcohol will increase the sedating effects of the sleeping pills. These combinations can be dangerous so it is recommended that you do not drink when taking sleeping pills. Talk to your physician about drinking while taking any medications to be safe.

And can kill you: Alcohol is contraindicated with any and all sleeping medication, as well as any other central nervous system depressant, like benzodiazepines, barbiturates and many others. The combination may not just be additive (1+1=2) but synergistic (1+1=5), where small amounts of alcohol together with sleeping pills can cause respiratory depression and even coma and death. Alcohol also causes sleep problems.
