if there could be any reasons for nutrition to play into your health scenario, there's a ton of related research available to help you.
regardless of whether you have ms or something that looks like ms, there is a common set of nutrient imbalances that are prevalent in patients with ms and other illnesses.
zinc and magnesium stand out to me based on your list of symptoms. zinc for memory, libido and dizziness. magnesium for involuntary contraction.
eating right can be pretty challenging. if you were to post or pm me a detailed list of foods and fluids consumed over say a three day period, i could scan for potentially troublesome gaps or interactions.
here is a link to resources on nutrients, testing, target levels, food sources and supplements. i collected the info based on imbalances in ms patients but the targets are cross cutting, just what are seen in research looking at 'healthy controls' as the ideal or optimal range, as distinct from 'normal' (otherwise known as the average in a small local sample of unhealthy patients). regimens-f22/topic2489.html#p15460
