Withdrawal: Has anyone ever experienced, "The Tunnel"?

Hello! I'm a little new to posting, so please bear with me. I (42F) am addicted to methamphetamine and will soon embark on yet another attempt to get sober, and I'm terrified. I've noticed that just like my patterns and behaviors in active use have evolved over the years, the withdrawal process has also followed suit. Every time I abstain, that process gets more intense, lasts longer, and is getting more difficult to navigate. An interesting phenomenon began about a year and a half ago that's more physical as opposed to mental or emotional. The closest I can get to describing it is it's like I'm trapped in a tunnel. Certain senses are heightened and others are subdued, but the worst part is I'm constantly disoriented to some degree. My vision is out of focus, I can't walk in a straight line or accurately assess my surroundings. The vertigo makes me queasy and I end up with symptoms similar to that of the flu. It's definitely not going to put me in the hospital, but it does interfere with every facet of my day to day responsibilities, not to mention making the mind fuck even more severe and I'm at a loss as to what I can do about it, if anything. Has anyone else gone through this or something similar? If you would be willing to share your experience with me or have any advice or suggestions to get past it more comfortably, I would be grateful! Namaste xoxo
