tapping and fainting

an interesting twenty four hours... a friend of mine is learning a method of doing healing through mental imagery and tapping acupressure points. I can't remember exactly what it's called, but she refers to it mostly as "tapping". I agreed to be a guinea pig, as she needs to get some case studies under her belt. We had our first session together last night. We had a brief interview style discussion to begin with, so she could get to know what really gets to me about the MS, and to focus on my fears and frustrations. Then she got me to repeat what she said whilst tapping a series of pressure points. The phrases first used were very negative, such as "these damn feet feel coated in tar", but then went on to things like "even though my feet feel like they're coated in tar, I completely love and respect myself".
There was a bit more detail than that, but that's the gist. When I first started tapping, the base of my cranium suddenly felt really warm, and as it progressed I felt quite flushed, and as we moved towards the more positive statements, I started to feel quite euphoric. There was a point during the process, where you focus on your fears, and repeating the phrase "what if this is it?" made me feel like I was going to cry! That's not unusual at this stage, apparently. I think if I had done this exercise three weeks ago I would have been howling at that point; that's why I think that I was so euphoric - I felt the emotional response rise in me, but I found myself resilient, and it said to me that I really have reached a point of resigned acceptance of my lot!
I don't think I showed much in the way of any physical benefits/changes from this first session, though I think she's planning to dig a little deeper next time (I am a tough nut to crack!).
Interestingly, and quite alarmingly,I fainted on the night I did the tapping, several hours after. I had a bit of a headache when I went for the tapping, it cleared up whilst we were doing it, but then came back later so I went to bed. I woke up in the night feeling really thirsty. I went to the loo, had a drink, then went for a wee. As I sat on the loo I could feel myself starting to have a whitey...I was nauseous, my head was spinning, I felt really disorientated, my heart was racing. It was quite scary, I hadn't been drinking or anything, and I'm not on any meds, but it felt like I was really out of it. I eventually got it together to grab a pukey bowl and head back to bed when I must have very briefly fainted. I was conscious again by the time I hit the floor 'cause I remember the loud thud and wondering why I had fallen over. I was very lucky! we have a tiny bathroom and I fell towards the sink, with only about 2ft between the sink and the door...I don't think I got one bruise to show for it though! graceful or what?!
When my husband heard the bang he came running, and was knocking at the door straight away. I hauled myself up to a sprawled sitting position and unlocked the door. Somehow he managed to squeeze into the bathroom to rescue me and get me to bed.

Now I am not ascribing this episode to anything in particular. But I have never fainted before in my life, and I have had many whiteys, for one reason and another. But it is an interesting coincidence that I had my first tapping session on that day...and the lady who led the session with me asked me to let her know of any perceived effects...hmm!
