I've done it twice and never again. BFF and I would rather chew glass.
On my last solo trip I told myself I wasn't going to be a chicken, it was silly, and that I was going to get on that darn thing and conquer my fear. Got up to the line and my knees started shaking, my heart started pounding, and my inner voice began shouting a word I can't put on a Disney forum! I walked away thinking "maybe next time".
The thing is, OP, you have to decide if the experience is worth it to you. The two times I rode it were 'worth it' to me but I won't do it again (unless I do, ha). The first time I had no idea what I was getting into. The second time I couldn't believe I'd freaked out so much the first time and wanted to 'prove' to myself that I was silly, but I proved I wasn't lol. If it would ruin your day (nausea) or if you would be harmed mentally or physically (full on panic attack, possibly physically freaking out) then don't do it. But if you think you would just breathe hard, have your heart pound, and shed some tears in a 'get me OFF this thing' fit but would be able to calm down afterwards (perhaps with the help of a cold drink of your choice), then go ahead and try it.
