Hopefully you have found some answers by now. I was plagued by internal vibrations for about a year. I think I may have found the culprit causing mine, but it took a while getting there. If you found the person on here talking about waking up several times in the middle of the night to cover up a little dog, thinking it was him shivering -- that was me. I was apalled to find out it wasn't him because that only left me. I went the round-a-bout way of getting there, BUT, I was not drinking enough water. I am very active outside with yard and garden, even now at 75; plus I walk 2-3 miles a day. My electrolytes were getting out of balance constantly in the summer months but I did not realize, for me, that was causing the internal vibrations. I had no idea they existed, until I got on here looking up "internal vibrations." When I was laying on my back it felt like I was in a vibrating bed. I had no idea it was me. I started searching everything dealing with gastroparesis, but no link to internal vibrations, then I thought I would try a "liver support," pill to see if @72 my liver could use some support. I tried a pill put out by Live Conscious, for liver and metabolic support, called "Liverwell." The first day I took just one capsule -- I was doing some paperwork about 45 minutes after taking it and I realized I had no vibrations in my shoulders and back. I thought it was a fluke, but 2 days later I had no vibrations. You are only supposed to take this stuff 3-4 months at a time and take 4-6 weeks off. When I stopped taking them I got some brief spurts of vibrations again, BUT, realized when I was not taking Liverwell, I also was not drinking the 2-3 quarts of water a day that I need. It has worked like clockwork since. If I start feeling vibrations, I grab a Smart Water to help balance on my electrolytes and I force myself to drink more water. At 75, you don't feel like drinking 2-3 quarts a day, not to mention if you don't get it in before 6 p.m. at night, I am awakened by a full bladder screaming at me, & at this age waking up in the middle of the night, often means staying awake!!
So, I would suggest trying something so simple -- Smart Water, Gatorade, if your sweating a lot to balance out your electrolytes and whatever amount of water you are supposed to drink for your age and weight. Then keep up on that daily water, because when I slack off, I will feel slight vibrations trying to return. Otherwise they are GONE, 100%.
