Hi Joyce,
No, after two years your can't stop hormones. You must continue to take your hormones for life otherwise your body will try and revert back to male.
If however you have had SRS, you can take a lower dosage but you will still need to take them.
The healing process for srs is quite long. It is major surgery. You will not be able to do heavy lifting for many weeks. You will not be able to have sex for at least 6-8weeks including anal sex. You will also have to dilate for the rest of your life. This involves inserting a dilator (like a glass dildo) into your neo-vagina regularly to make sure is is kept open. It is an artificial hole and will try to close if you don't. Having sex is not enough as a penis will not strecth the vagina to its natural limit.
There is plenty of information online regarding post-operative care for srs.

Lots more on Google.
