The Most Addictive Over the Counter Drugs
2. Sleeping Pills

Many individuals struggle to sleep and in turn, they rely on common sleeping aids. Once desperate for a good night's rest, many begin using sleeping aids on a regular basis. These pills are only intended for short-term use, which is why an addiction can develop so rapidly.
Users become reliant on these medications and quickly need them in order to sleep. Once abused for an extended period of time, extreme withdrawal symptoms develop. Some of the most common withdrawal effects include tremors, nausea, and sweating. In some cases, discontinuing use makes sleeping difficulties worse.
