Advice/comments for new MG diagnosis and possible treatments

This is quite long, but if you have time and can share any thoughts, I would be very appreciative.

New MG diagnosis and would like some opinions on doctor's advice. I'm a 54 year old male. My problems were swallowing, speech garbled and eyelids drooping. 10 days in the hospital and on a feeding tube. IVIG treatment started right away seemed to help some, but not a lot. Left hospital on 20mg prednisone, increased to 30mg after a week, then 60 mg after another week - this got me back to swallowing and talking normally after a couple of weeks at 60mg. A second IVIG treatment did not seem to do anything, so I chose not to have more of those treatments. After a month on 60mg prednisone, start to taper off. 40mg for a month; 20mg for a month; 15mg for a month; 12.5mg for a month; 10mg for a month; I'm now at 7.5mg. Doing okay throughout the taper. Still get tired quickly and easily when doing physical labor, but otherwise doing okay. Just saw my neurologist about what to do now. His recommendation was thymectomy and steroid-sparing drug for the rest of my life. I don't want either of those. Chances may be small, but they have some serious potential negative consequences I would not want to experience (cancer being the one that comes to mind first). I understand this might be a pipe dream, but perhaps I could be a case of someone who can get my with no surgery or drugs if I'm careful. I told him I wanted to try to get completely off prednisone and do nothing else until I see if I could do that, using Mestinon if needed (it seems safe). Here's what I'd like your thoughts on:

1. His taper would be 7.5mg for two months; alternate days of 7.5 and 5mg for two months; 5mg for a year and see how that works. I failed to ask why a year before dropping further. I want to speed this up: 7.5mg for a month; skip the alternating and in month #2 do 5mg; then maybe drop 1mg each month as long as I'm doing okay. I realize chances are I'll start having problems and have to up the dosage and start the taper over, but I want to find that out. Or at least find out what is the lowest dose of prednisone I can take and maintain how I am doing. I know Prednisone has negative consequences too, but I think I can manage those and feel those consequences are better than getting cancer. I think I'd choose long-term prednisone treatment at 5 - 7.5mg over surgery and steroid-sparing drugs. What do you think?

2. Two or three years before the diagnosis, I started getting tired very easily and quickly and could not do all I had once been able to do. I found myself needing to sit down to rest while shopping, being winded after climbing a flight of stairs, and having to push myself to do various yard work which I do a lot. I told my wife I felt like what I think an 80+ year old man feels like. My sleep isn't the best, but I can't see that would be the sole cause of how I felt. My regular doctor did various tests and could never find anything. When I told him recently I was diagnosed with MG, he said how I'd been feeling now made sense (but he's never had a patient with MG). Here's my question: my neurologist said this has absolutely nothing to do with my MG; that whatever it is would be something completely separate; and that in getting old this happens. I know as I get older my abilities will decline, but this decline has been very significant and I don't think is a normal declining. When I left the hospital, I recall being told to take it easy and let my body tell me when I should stop and rest or I could have another crisis, but now he is telling me there is no connection and I can work as much as I want no matter how exhausted I get - that it would not cause me any problems or send me into another MG crisis. I will say this though: on 60mg prednisone versus 7.5mg now, I can't tell any significant difference in how I feel; at higher doses I didn't feel any more energetic or need to rest any less than I do now.

Any advice or comments or suggestions are appreciated.
