Hi Julie,
I have not seen anything about doing them together but I find the concept intriguing. Getting the ganglia calmed down at the source and then following with ketamine...Kinda cool.
As for the trip. Taking soothing music with you is helpful. Also just staying calm through the weirdness. My last infusion was the most "trippy" because we lowered the Versed so I wouldn't be so tired. I had a lot more visual effects of swirly geometric color patterns behind my eyelids (I keep my eyes closed because my vision is so blurry on it). I found a couple times that I wasnt liking it and noticed my heart rate speeding up a little. I made a point to take deep breaths during those times. It was strange but not intolerable and not really agitating for me personally. Feeling more alert the rest of the day was worth the trip.
Relax, know you're in good hands and let the healing come. I will be thinking of you on Tuesday and sending healing love.
