@angie The guide explains how to "build up" your meto test, so you test the full actual amount you will be using.....
It's worth reading the whole "Notes" section of the guide (only 1 page), but here are the bits relating to what we're discussing now :
During your "planning" phase, a meto "test" should be done, using 1 x 10mg, to see if you get any "EPS" symptoms (involuntary moments/spasms), which could sometimes be sufficiently severe/disturbing to prevent any attempt. Most people don't get EPS, but if you do, then you may wish to re-evaluate (eg switch to domperidone anti-emetic). Apparently 50 mg of Diphenhydramine (Benadryl) can be used to treat EPS, so it may be wise to have that on standby. See "wikibooks antiemetic regimen" below for more info.
Further meto testing notes : If planning to use the 30mg stat regime, if testing with 1 x 10mg goes smoothly, you might later wish to test with 2 x 10mg, and then later with 3 x 10mg. If planning to use the 48 hour regime, if testing with 1 x 10mg goes smoothly, you might later wish to test 1 x 10mg every 8 hours for 24 hours. To be as certain as possible, you could re-create the full meto schedule you plan to use.
NOTE : When you first start your "meto testing", you may wish to start with only 5mg for extra safety ( in case of EPS symptoms).
If that goes smoothly, then you can later test with 10mg, and so on, as described above.
