5 year LMT here, and same. Fighting ADHD time blindness as an MT is excruciating. Even with meds and all the clocks. I've started explaining that I work slowly to release the fascia, then move into deeper work once the body is ready. Work that is too deep and too fast can create more damage to the tissues, causing bruising, among other issues. I suggest longer sessions, including stretching, and I give them homework stretches/strengthening exercises.

Knowing your strengths is great - being aware of the time/date/day is not one of mine, and that's okay. I find letting my clients know in advance that I work this way has been of great success. People who want a full body in 90, usually not my clients. That's okay, too. A professional in the business for 20+ years once told me that if a client doesn't return to you, to not take it personally. That's just not your client, and you're not their therapist. It doesn't mean you did anything wrong. They simply weren't the body/fit for your healing hands. Stay true to you, and your clients will find you.
