Oh losing your sense of hunger can definitely be an MS thing. When I first noticed it, I "tested" if I really lost my sense of hunger.
So I stopped eating just to see if I got hungry -- I kept drinking things, of course! It's dangerous/stupid to stop drinking.
On the morning of the *6th* day I woke up without the slightest "pang" of hunger, I then decided I was being stupid and I didn't have a sense of hunger any more.
So today I "eat" by routine or by timer.
I can miss food for days . Now I try and stick to an eating routine,
Well done Dave.
I keep protein shakes and quick small meals we need food to build strength and energy.
Just saying the doctors will prescribe you marijuana which will increase your want for food but I would talk to a doctor first to see I've never tried while on MS waiting to talk to a doctor first
