Feeling weird

So I've made it to day 11 for the first time! Having very intense fantasies, doing my best not to get carried away by them.
I've been feeling increasingly speedy over the last couple days, and also having intense insomnia, waking up throughout the night.
Although my MO addiction was never too bad, I have done it all my life so I can imagine that my brain is adjusting.
Part of my is a little worried though because I feel pretty weird and am also having some physical symptoms like occasional tingling in my hands and feet.
I take several supplements and part of me is worried I messed something up in my brain. I probably just need sleep lol.
Can anybody relate to my experience?
