I have been diagnosed with CHF also but I do not have that symptom. But I am in the early stages and have some conditions that thankfully prevent a lot of things other have to do through.

I have heart failure and I sweat often. Happens more in cold weather

I had the sweats in the beginning and if I eat too much soduim that happens.

I have done this, more so at the beginning of this journey. Also some really odd dreams sometimes, which still continue. I have always been a vivid dreamer but these are very detailed, sometimes really good and sometimes wow bad and have those nightsweats with the bad ones. Hope that helps.

I have had CHF since April 22, but take Lasix and Metoprolol, beta blocker, since my triple bypass surgery. Have not had any more problems with retaining fluid.
Hope you have a restful night and a good week. May God bless.
