Hello. I am responding here, rather than privately to the PM you sent.
This sucks. I feel for you. If you are going through what I did, then it was as bad as the initial crash, in a different way.
The good news, I am very much improved in nearly every aspect. 6 hours of sleep per night is now attainable, with only 1-2 brief interruptions, and I don’t feel amped-up or strung out during the day any longer. Derealization is gone. Frequent urination, gone. Libido and ED are back to where they were before taking the SAMe and Me-B12.
The bad news, it took 4 months to get over the worst of it and my sleep is still disturbed somewhat 8 months later.
No matter how bad this becomes, tough it out. Just be prepared for a terrible few months as a worst-case scenario.
