If you ever get your hands on an Ascension-tag, you will have some very “harsh” first few months. Nothing compared to the regular fields above 
Point of No Return can be a little draining in the beginning.
But the draining in these comes mostly from you getting rid of low vibrational aspects of yourself and your body and also detoxing. So afterwards, you will end up on a new higher vibrational baseline. So totally worth it going through the process.
This applies to all fields that somehow raise your vibrational state.
Not sure why these would drain you?
Aren’t these supposed to rather do the opposite…
I also made a thread a while ago about fields for restoring sexual energy – please feel free to add your experiences there as well:
