Been to government hospital today, since I also suffered from a bad cold. Doctor prescribed me some medicines for cough, a mucolytic medicine to release mucus, and a 30 day supply of 2mg Diazepam. Total cost was 364 baht. When looking up all those sleeping aids mentioned in this thread, and including Diazepam of course, I start to feel uncomfortable since all of them mention this. Interactions: It interacts severely with alcohol, opioids, and other CNS depressants, which can lead to profound sedation, respiratory depression, coma, or death. Withdrawal Symptoms: Stopping the medication abruptly can cause severe withdrawal symptoms, including severe anxiety, insomnia, tremors, muscle aches, vomiting, diarrhoea, and in severe cases, seizures. Half life of Diazepam is long, I can read this Duration of Action: While the half-life is long, the immediate sedative effects generally last 4 to 6 hours Will see how it goes but on my next appointment I probably ask for something safer. The reason why I didn't have side effects from the Diazepam I still had is that they were only 1mg, and were expired for 15 years already, so they probably had lost most of their potency.
