If I have been binging for more than 36 hours without proper rest. whenever I eat something SOLID it does irritate my mouth, like a burning sensation and sorta like cold sores... This is due to immune deficiency while tweaking a long with compacting other side effects of Amphetamines with it... Best advice is to stay hydrated, stay with plenty of nutrients and try to control the binge...
Stay safe, stay informed... And if you would like to me to elaborate more because I KNOW what you mean, but it's only with amphetamine products, Desoxyn(d-meth) has NO SIDE EFFECTS whatsoever for me.
