Can you dose after microdosing? How much time should you space between doses?
Everyone is different. I’ve dosed the day after microdosing. I’ve microdosed the day after microdosing. I always felt the effects. It always went well. Some people report short-term tolerance and the need to take a little more to feel an equivalent effect the day after a (micro)dose, but I wouldn’t necessarily advise that here. Wait a few days if you can between doses. Or, figure out why you may feel the need to dose so often.
(The Fadiman microdosing regimen recommends one day on, three days off. So if you want to take a big trip within a microdosing regimen, try sticking to on/off days, whether the dose is micro or not.)
How long will it last and how quickly will I feel it?
