I was attracted by your post title, I know it´s been some time since you post it, I´d like to know who did it went on for you.
Personally, I think DMT doesn´t make you more "enlightened", (as Zikzak mentioned), I think that is an ilussion of your ego, that you somehow become a better or wiser as a result of phychedelic use.
It reminds me of a funny guy on youtube, ( "AwakenwithJP" ) he makes satire out of spiritual trends, one of his books is called "7 ways to be more spiritual than your friends". Check this vid LINK
I think you should go for the full DMT experience, specially if the spice is telling you so.
You will still be yourself, being aware of what ego is might give you some insight and make you a better person (unless you have a promising carrer on politics).
I´d like to finish with some question regarding "cheating".
Marriage is a contract or commitment with other being, the contract expires at the moment of death ("...till death do us part..." ) .
So... what or who is your wife really commited to?
1- Your physical body?
2- Your personality?
3- Is your ego the same as your personality? (for budist the "monkeyvoice" is actually the source of suffering)
4- Your soul?
And if DMT grants you access to the information of soul, re-incarnation and life after death, wouldn´t you want to make your wife experience that (make her smoke...) at least once before she dies... I mean, if death is not the end, that makes the experience of having people close to us dying much easier, no unnecessary stress or suffering for a loved one when the end of the road is near.
