How long do I wait for Indica capsules to kick in?

Assuming you're only taking one or two capsules a day, it seems like you are taking a very low dosage for something with severe symptoms. It's good that your sleep has improved, at least you have evidence that your body responds well to the CBD. This means that you should be safe to increase the dosage.

One of the most important things about using CBD products is finding discovering what dosage and methods of consumption suit you best. Everyone is different, which means discovering what works for you boils down to a lot of trial and error. I would say increase your dose of the indica capsules for now and see how you respond over the next week.

When your oil eventually arrives, experiment with one in the morning and one in the evening, alternating between the two and steadily increasing the overall daily dose by 5mg each week. Most people who do experience the benefits of CBD products do so within a few weeks, so if you haven't yet it's either because you won't at all or because your dosage isn't high enough.
