insomnia
"Suvorexant 20mg worked excellent until abnormal adverse effect of hives started approximately week 4 into therapy. It works well for me other than for the hives that prevents me from taking it. 

I miss being able to sleep like I did on Suvorexant. I am looking forward to SORAs allowing me to sleep normally again like I did while on Suvorexant, but hopefully without the problem of hives, which I may be the only person known to get hives from Suvorexant. Loratidine resolves the hives but so does ceasing Suvorexant, so I stopped Suvorexant and am once again a miserable insomniac...

Thank you Merck and all chemists and scientists for a brief period of relief and some hope that normal sleep is possible. This was a good drug, but not for me."
