Withdrawals are the worst... putting it simply... as an understatement...8(

I've gone through severe withdrawals from opiates, benzos, alcohol, nicotine, methamphetamine, actual heroin, was depressed after quitting weed for a while (was smoking about an ounce a week or more for a few months-it was really potent stuff from when I lived in San Francisco. Most of this was.
The absolute worst was the benzodiazapines. I had seizure activity. Severe muscle cramping, & it didn't go away very quickly. As benzo withdrawals can fe fatal due to the high probability, and the fact that you're almost guaranteed to at least get really bad ticks & spasms, muscle jerking, electrical zaps accompanied by severe muscle jerking/twitching &/or sustained seizures makes benzos the one that I'm really actually scared of.
The alcohol withdrawals was pretty bad too, but it's not like I couldn't taper off of it, plus I was able to get a rx for librium (a benzo often prescribed specifically for withdrawal symptoms) which seemed to get me through it. Plus alcohol withdrawals don't last nearly as long as benzos. Also, the slower acting your specific benzo is, the longer your withdrawals will last. So, like the Klonopin (Clonazepam) is a slower acting benzo. It's absorbed slower, doesn't peak quickly, or as high, because it lasts longer than the popular go-to benzo, Xanax (Alprazolam). Then the Valium (Diazepam) is also a slow acting, longer lasting benzo as well. Xanax is one of the quickest acting benzos, but doesn't last as long or stay in the system as long. I take Ativan (Lorazepam) 2mg 4x/day PRN. I've been taking it for almost ten years for severe panic attacks & insomnia.
You know people often think that heroin/opiate withdrawal is the worst, but it's far less likely to kill a person than benzo withdrawal or alcohol withdrawal. Not impossible, though. I have had tachycardia/palpatations/irregular, uncomfortable, scary feeling heartbeats that then cause panic attacks, amplifying my perceptions of what may really be going on with my body, so I typically try to just have enough ativan on hand to try to sleep through the withdrawals. Not to mention that benzos definitely help with any withdrawals
After that I no longer felt ok using the scooters, yet I must use it if I want to get my groceries. Now that I have a cane I can leave in the basket of the scooter, I think that perhaps I won't look as strange using the handicapped equipment to get around & parking in the handicapped parking spaces. Plus I really do look younger than my age, now 34, than I am... especially in the face...
