Alcohol+Amphetamines
Caution

These combinations are not usually physically harmful, but may produce undesirable effects. Use caution.

Note: Drinking on stimulants is risky because the sedative effects of the alcohol are reduced, and these are what the body uses to gauge drunkenness. This typically leads to excessive drinking with greatly reduced inhibitions, high risk of liver damage and increased dehydration. They will also allow you to drink past a point where you might normally pass out, increasing the risk. If you do decide to do this then you should set a limit of how much you will drink each hour and stick to it, bearing in mind that you will feel the alcohol and the stimulant less. Extended release formulations may severely impede sleep, further worsening the hangover.
