Severe vertigo colonoscopy prep

Hi everyone,
I know this topic was covered a little bit in some older posts but I was wondering if anyone has anything new to say about their experience with colonoscopy preps.
I get episodes of very severe vertigo, the attacks come in clusters with a month or a few months of remission between episodes. My vertigo lasts for 17+ hours at a time and the cluster of attacks can last for many weeks to months, my longest being 7 months with out leaving my house. They're so bad that I can't move a millimeter during an attack, I vomit every 3-5 minutes and I have to wear Depends because I'm unable to move to use the restroom, the whole experience is traumatizing to say the least, Valium and Zofran don't do much for me.
I am supposed to get a colonoscopy next week and I'm terrified to take the prep solution before the procedure. I cook all my meals from scratch and do not add any salt in any of my meals ever, the only sodium I get is from the liter of coconut water I drink a day and any salts that are naturally in vegetables and organic meats. The colonoscopy prep solution that the Dr is prescribing is called GoLytely (4 liters of fluid) and contains about 30,000mg of salt that I'm supposed to drink in 2 sessions that are a few hours apart.
My Dr can't recommend anything else better for my meniere's and I was wondering if anyone had a Dr prescribe a special prep for their meniere's that's maybe low in sodium? Or I'd love to hear anyone's experience with the colon preps. Thank you for your time!

 

Thanks Mpoje, I asked about taking Miralax and the dr didn't seem to think it would do anything. I may need to get a second opinion.

 

Thanks IvanA! That's a great suggestion, I'll see what the dr says.

 

Hi IvanA,
I'm not totally sure if sodium alone is a trigger. I do know that when my electrolytes are off balance I have severe attacks, I've had attacks when I've been dehydrated and once when I tried Smooth Move senna tea which cleared my colon out but threw my electrolytes off which put me into the worse attacks of my life. Stress is another definitive trigger. A few months ago I tried to add saltier foods to my diet but ended up having attacks, there were also other variables involved, stress for one, so it's hard to say if it was the salt that triggered the attacks. I'll need to try testing my sodium tolerances again.
I was diagnosed with meniere's 3 years ago, with my first cluster of attacks was after going freediving in the ocean.
I have 2 neuro-otologists, one at UCLA and one at the House Clinic in CA. I'm taking 16mg of Betahistine 3x/day for 2 years and I'm following the JOH supplement regimen. I tried diuretics for a year but they didn't seem to do much. I'm also avoiding some foods that I was slightly allergic to (I did allergy testing at the House Clinic), I'm on a very low salt diet and I'm also avoiding foods high in lectins which can cause inflammation. Cutting the foods high in lectins and the foods that I showed an allergy have made a difference I believe, next I need to test adding more sodium to be sure of how it affects me.
If I can keep my stress levels down, electrolytes in balance and get plenty of exercise I can go a few months without attacks. But when I have one, they come in clusters and are very severe. I'm getting a second opinion on the colonoscopy prep tomorrow, fingers crossed they can offer something more mild.
I'm really appreciate the time everyone took to respond to my post, thank you.
