Hello again.
You can continue with the 6 hourly dosage. Extending it to 7 - 7 and half hours probably won't make a significant difference to the tapering process. It will only extend the time when you have to take the last tablet of the day, which can affect your sleep schedule.
Keeping 3 tablets a day schedule, you can reduce the dose to 0.25mg. After two weeks, you can further reduce the dose by half. You might have to look for 0.25mg tablets, which you can break into half. You can even go a bit slower by dropping off the afternoon dose and continuing on 0.25mg twice a day for another couple of weeks. The more gradual the better.
This is a rough guide. I suggest you discuss with your doctor regarding the feasibility of this plan.
Hope this helps with both your questions.
What is your medication that you are talking about? what was your normal dosage? and why do you want to come off?
