If you have to think this much about it, you probably should take them. At least that is what I usually go by when it comes to such things...if I have enough doubt to stress about it I don't do it, but would be lying if I said I was opposed to psychedelics. It is important to be safe and in a comfortable setting if one so chooses however though...

I also do not have bi-polar and don't know how that effects the experience or not, but good rule of thumb with psychedelics is if you're thinking of reasons why not to, then probably means you're not in the right place in my opinion(which makes a bad trip more likely and those aren't fun obviously) regardless of specific diagnoses or lack of diagnoses.
