Thanks Sue! I PM'd you.
Ah. I assumed you would use a consistent dose/etc, so it wouldn't make any sense to chart it. I guess if you're experimenting with dosages, administration time, etc, it would be useful to record that.
LOL!! Between you and Sue, you're going to convince me to do the injections!! 
Do you have to get a script for that from an MD, or...?
Yeah, there are definitely differences. I experimented a bit with the WF drops and they worked, but they didn't seem to work as well as Readisorb. But that was when the B12 in general was losing effectiveness, so I'm not sure about cause/effect. But I can't get any Readisorb for a week or more, so hopefully something's better than nothing.
I don't think Readisorb is a physician-level supplement -- you can order it on Amazon. (Hm. I guess you can order it on Amazon if you're in the UK. But it is available online from other US vendors.) It just seems to be very effective for me. As I said, when I've got symptoms driving me bonkers, I can feel the effects within minutes. I'm not sure how it compares in effectiveness to Jarrow 5mg, which is what I've been using lately. If Jarrow hasn't been fixed since it "went bad," Readisorb might be a lot more effective. I should get some of the recommended Enzymatic Therapies 1mg and/or Country Life 5mg. Or join the rest of you addicts and start shootin' up. LOL
"charting" means track how much you take of each type of B12 each day, every day, when you take it, and precisely how it makes you feel (good, or if bad, what symptoms are manifested). If you do this for a period of time you will begin to see a pattern emerge and will thus be able to hone in on what works for you.
Shots are not bad. I was fairly intensely afraid of needles before I started using my beloved crack injectable methylcobalamin.

Not all B12's are created equal. If your Readisorb is a physician quality product you may find a big difference between it and the drops you buy at Whole Foods. Just saying, don't be surprised if you have to shop around for products that are effective for you.
