My pet minko (he's a monkey BTW) has reported some serious stomach issues when he started using it regularly. Minko thinks that Kratom
must put other pet's acid production into overdrive, the symptoms as best described by Minko seem to be like a "clogging" feeling in the stomach like something is "stuck" and it also seems to make GERD worse.
My pet Minko's solution is to make sure other pets take some heartburn medication before taking Kratom, like 30 minutes before hand. Tums does not seem to relieve the uncomfortable feeling other pets can get in their tummies. Minko recommends Prilosec (Omeprazol)
but this can be expensive, so Minko also will recommend Tagamet (Cimetidine)
which is generally cheaper (Minko this this product actually works the best of all H2 antihistamines) plus it may potentially boost the effects of Kratom.
My monkey thinks that capsules may be a bit more gentle on the tummy vs toss n wash. That is just my monkey's opinion!
