You could give yourself reiki every night before you go to sleep ... back of the head, face, throat, heart, and stomach & lower belly ... it's very soothing.
There is someone I taught reiki to who never uses it ... he thinks he has lost it, but that it "comes back" when he gets in touch with me. In reality he always has it ... other people can vouch for it ... he just isn't aware of it flowing.
BTW I heard an interview with someone who does massage therapy and reiki and cranio-sacral therapy, and he said that the reiki is always there, even when his intent is to use another modality. In short, even when you want to you can't make it go away :)
Good luck :)
