Alternative ways to "activate" kratom
Hello all! First time poster here, long time kratom user.
My question is about ways to "activate" kratom once it's been taken. I almost always take capsules instead of straight powder, and I've found that unless I eat or drink something, I won't feel the effects of the kratom. Unfortunately, I started drinking Coke as a way to get the digestion (I guess?) started. Now for years I've been drinking upwards of 4 cokes a day, which is not good. What I like about the coke is that it seems to activate and maintain the kratom effects, probably because of the caffeine (I also drink coffee with my morning kratom). This could also just be a placebo effect after years of associating drinking coke with the positive effects of kratom, I'm not sure.
Anyway, I'm looking to start a keto diet with my wife (the years of cokes are finally catching up with me :D), so cokes are off the table. I could drink diet coke, but I'd rather get away from it completely while I'm motivated. I've gone through a few cycles of drinking grapefruit/orange juice mixed with club soda as an alternative, but those juices aren't compatible with the diet either.
Long story short, does anybody have any recommendations for what I can replace the coke with? I'd like to avoid eating anything to keep my stomach empty, and I'd love it if I can keep the effects sustained for a while like I get with coke. Any help would be appreciated!
