OK - that is useful - so give or take, we can call it 1% = 1 bead.
Therefore, 10% would be 27mg and would be 90 beads. That would be a safe starting point as you have only been on it a month. I would recommend you give that at least a week and see how the symptoms go. This will then dictate how you can then proceed to ween off the rest.
Following this, it would be a case of a similar pattern until you get down to 10mg, then the brakes need to go on regardless of how well the previous 20mg have gone. Trust me. The last 10mg nearly always catches people out.
If you change pills supplies, we need to re-evaluate by counting beads again. No 2 capsules from different pharm's have the same number of beads.
