Thank you for that extra information and, once again, please accept my apologies for my first response being eaten by the internet :(
My first thought when you told me about what is going on is that you have MS. Since this is, indeed, the case, no further workup is necessary concerning the etiology of your droopy eyelid.
I would strongly advise you to have the diagnosis of MS confirmed by a neurologist if your ophthalmologist and GP feel this is still needed.
Concerning your eyelid, since your ptosis
(droopy lid) is intermittent and recovers full function after an episode, I would not recommend any type of surgical correction. If this were done you would have severe over-correction during your "normal" times, which could cause corneal exposure and severe damage to your eye.
The best way to take care of these episodes is to adequately treat your MS, diabetes and other medical problems.
Should your ptosis become consistent in nature and permanent then, and only then, would I explore surgical intervention.
Does this make sense to you?
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. You may also receive an email survey after our chat, if you don’t feel that I have earned a “10” rating in all areas, please let me know what I can do to meet your expectations.
Thanks in advance,

I'm going to make a copy of this answer in Microsoft Word just in case the silly Gremlins eat it too! Thanks for your patience.
I wish you the very best.
