Hang on Jules. Take a deep breath first of all.
I've been in your shoes and while I don't have all of the answers I might be able to help you decide how to handle this. I need to finish my work day but will post in a couple of hours.
Jules,
First of all pls know I know what it is like to take MASSIVE amounts of benzos. I had very legit anxiety in a bad marriage and it snowed way out of control! I won't make this reply all about me but trust me. I know.
I also know it is very scary and lonely to worry about your pills/withdrawal/hiding/being outed and all of the other things that go along with addiction.
That said, your first order of business needs to be finding some type of benzo. It doesn't have to be klonnies and in fact, I would recommend Val's. If you placed a SY order today you will be very lucky to receive by Friday or Saturday. Assuming you have 4 days of pills (at your usual 20 mg per day dose) remaining, you are covered through Sunday, correct?
If you are relying on a SY vendor you are going to be cutting it close. Do you think you will get a real overnight order? I thought those guys were averaging 3-4 days. I'm thinking a SY order placed today would arrive Monday unless you are super lucky. I really don't know... Just playing devils advocate
I would recommend you cut your dose by 1/3-1/2 so you can at least hang on until your SY order comes in. This way, while you may be really miserable with less medicine until an order arrives, I doubt you would seize.
Now, if you do run out of meds you can fake a panic attack (you actually won't be faking) and get a few from the ER but not enough to hold you at the doses you are taking. I doubt you could get more than #12 (5) mg x@n@x from an ER doc and that will hold you until noon.
The risk of seizure peaks around day 3-4 and can last for up to two weeks if you CT off benzos. And it is very very real. You are at a high risk, Jules. Don't think "it won't happen to me". I was on about the same amount and seized on the morning of day 4. (Thank GOD I wasn't behind the wheel.).
About tapering... Taper with Val's not x@n@x. But (and this is a BIG one) be honest with yourself. It is extremely hard to self taper. Given the sheer amount you are on, I don't think your GP will agree to supervise a taper even if you come clean to him.
I started 100+ tapers during the 7 years I was on benzos. I was successful with ZERO and I don't think I was in the minority. It is hard to get off these things and you really do need physical and emotional support. I DO think tapering is the most comfortable way to get off of them but I also think it is next to impossible. It will NOT be quick, that's for sure. You are looking at continuing IOP ordering until you are down to your prescribed dose. Probably a year if you go slow enough to stay fairly well.
Are you familiar with the Ashton Manuel? If not, google it. It is like the bible of getting off benzos. Also, there is a forum called Benzo Buddies that is all about trying to taper off benzos. Lots of support there also.
Finally, I promise you rehab will NOT ruin your life. Oh, it will be embarrassing; surprise friends and family; might even generate a few whispers behind your back. But, it won't ruin your life. Seizing behind the wheel and killing yourself or someone else will ruin your life. Driving while impaired and getting a DUI/possession charge will ruin your life. You get what I'm saying.
It isn't actually going to rehab that "ruins your life".... It is catalyst (see above) that gets you to rehab that ruins lives. Think about that.
Here is the thing. The people close to you already know something is wrong. They may not know what it is but they know something is up.
Good luck and order some Val's. Seek immediate medical attention if you are see you are going to be 24 hours without meds.
And try to taper. Read the Ashton Manual. Feel free to PM me if I can help you in any way. You can do this one way or the other and eventually you will have to face it. Lots of freedom when you finally do.
