Reversal how long should I wait?

As most know here I had a LAR August last year and before the op I was told two to three months however with the Covid situation it would be six 

I had the blue dye test January that showed I would need an EAU to check that all was clear for a reversal. I was also told at my follow up that they thought that whilst under a GA if all was clear they would reverse me. 
I thought that makes perfect sense as why have two lots of GA but it would mean I wouldn’t know before going in if I was able to be reversed. So I was told I would need a pre op

That was January 

Previously my surgeon had said that reversals are best at two months and a maximum of six. Twelve months was not so successful

So here I am a couple of weeks away from the year and all my diary dates that were planned have been deleted. There’s not going to be a colonoscopy August because I haven’t been reversed. I’m waiting for a CT scan appointment and my CEA levels are due August 

I am in a state of limbo really 

How long did others wait before having a reversal and if over twelve months was it really difficult to gain bowel control? 
Im seriously thinking of not bothering and booking a holiday!
