Does anyone else who takes narcotics/benzo's experience these symptoms when they run out.?

Benzodiazepenes and Opiates (as you known) are both very physically and mentally addictive. Since you have been prescribed both at decently high doses, your body is experiencing withdrawals in between refills. While opiate withdrawal is extremely painful (I've always said its a hell that dante couldn't have even imaged) it will not kill you. I would look into either managing your dose so that there is no way you run out, or searching for different kinds of strategies to handle the in between days. The "Thomas recipe" is a great one. However, withdrawal from benzos can be very dangerous and can cause deadly side effects. Another point too, is that without the daily intake of benzos your body naturally can have more severe anxiety as a side effect. If I was in your position, I would have a chat with your doctor about options to decrease this horrible time in between. (When humans are born we have natural pain receptors in the brain that are very similar to opiates. When people start using synthetic opiates, the natural ones in the brain die off. Consequently, when you have no pain pills in your system, the normal pain seems 10x worse. Also on a psychological level, you are used to being able to get relief from your pills, and when they are not available you not only have to fight the physical pain, but the emotional anguish of not being able to make yourself better.) The reason you can go longer without the methadone is because methadone has an extremely long half life. Thus taking a lot longer for it to clean out of your system. Methadone is one of the hardest, most painful opiate to withdrawal from because not only do the symptoms last for more than a month in some cases, but also can cause psychotic episodes. Lorazepam is a shorter acting benzo, so it processes through your body quicker. I wish you the best of luck with dealing with this, and like I said, I would consult your doctor on ways to make this more manageable. Nobody wants to have to deal with a few days of absolute hell a month.
