Yoga / bodywork addiction - good or bad?

I don't have a disciplined 6-day Ashtanga practice.  Last year I established a semi-regular routine where I practiced some sort of yoga (Power or Hot) about 3-4 times per week. In December, I went on vacation in Asia for 3 weeks.  I had not been on a plane ever since I took up yoga, so I thought that regular yoga practice would help me settle easier on the plane since I had become more flexible over the last year. I was completely wrong. On the plane trip back to Asia, I kept feeling this great desire to stretch. I couldn't stop squirming around in my seat, doing hamstring stretches, neck stretches, spinal twists, arm stretches, you name it. I left my seat about 3 times to the back of the plane where there was a bigger floor space and did every pose that didn't look too ridiculous, including forward folds, mini dancer's pose, mild triangle, more twists, neck circles, etc.  I felt like I had earthworms inside of me struggling to wiggle their way out.  After 3 weeks of doing almost zero yoga, my plane trip back to North America felt much more at ease. I didn't feel the need to wring out all my body parts like a towel and stretch them in every direction possible.

I didn't go back to yoga class right away and recently I'm just slowly building up my yoga practice to 2-3 times a week.  Now I feel and probably act like a squirmy earthworm again whenever I'm sitting still. Doing mild stretches just makes me want to stretch more. I blame it on the excellent Thai massages and deep tissue massages and Ashtanga adjustments I've been receiving the past year. I feel like my body is suffering from pamper withdrawal.  It's demanding more frequent deeper stretches, more yoga poses, and quality massages. It's as if I have a drug addiction. I'm worried if I keep on doing yoga, am I just going to become more and more flexible, and is my body going to scream at me if I don't wrap my leg behind my head at least once a day?  I thought committing to a more frequent yoga practice was the establishment of self-discipline, which would be a positive thing; but this feeling of yoga / bodywork withdrawal is kind of concerning.

For those who have practice yoga regularly for a few years (or decades), do you experience the same thing if you take a break from yoga for an extended period of time (say, a few weeks)? I look forward to hearing your opinions/experiences.
