hi,

yes, it is a rollercoaster.

itīs been a rollercoaster for me for almost 10 weeks now.

i am not a doctor but from my personal experience i would recommend you to avoid any strenuous activities/sport activities. it worsen symptoms and can cause serious relapses. NO alcohol. do not party. try to relax, rest and sleep as much as possible. no stress. drink a lot of water. eat brain friendly foods. make sure you are seenig a good neurologist (other specialists) about your symptoms. as far as "the other dimension" thing - you are probably talking about derealization (feeling spaced out?) and as far as i know itīs caused by anxiety. I have been dealing with that a lot.

anyway all the best

i hope u will be ok soon
