I am going to take 2 pills instead of 1 of zolpidem before bedtime. I can't see my doctor till next week. Severe insomnia. Will it cause CNS depreson?

Zolpidem. Developing tolerance to this dangerous and highly addictive medication means that more is not better or more healthy. It means you have used too much of it. An ever increasing dose of Zolpidem is not going to bring you real or restorative sleep. It is time to get to the sleep specialist to figure out your problem and to get you to a place where sleep is natural again. It means stopping Zolpidem.
