Ok, a few general notes from someone who's tried most of the strains (there are sub-varieties of the main red-green-white strains that are mainly marketing imo).

1. Reds are more sedating than greens, which are in turn more sedating than whites -- true, more or less; but this is very individualistic, and even changes over time... with me at least.

2. Kratom is constipating -- true; no way to avoid this in my experience; whether it's more so than pharmaceutical opiods is open to debate.

3. Kratom causes insomnia -- true for me; sometimes the reds less so than the greens and whites, but I haven't found a way to avoid it except to limit your intake to earlier in the day and/or go with whatever other sleep aids you like (e.g. 3 mg of Melatonin) I should add that my brother is also a kratom user and reports no insomnia issues.

As always I'm available via PM for anything else I can tell anyone.
