cosmoe, Ptosis is hard to manage. Only you can decide if you want more treatments in an attempt to make it better.
You can always have a small fan running on your face while at the computer (or do you just use a phone?). Keeping the eye area cool does help. And when you become heated up, cool down right away. A cool (not cold) washcloth on the eyes can help as well.
I tend to rest my eyes just by closing them, or by lying down for a few minutes. Of course, when MG is overall worse, not much helps with the eyelids. They are the first to go and the last to recover.
I wish I had more tips for you!
