Yes! I'm not sure you can officially OD - But you will get bloated, gassy, nauseous and probably have D.
The 1st time I took fiber I took a full dose (2 pills) and was up all night with D, gas, bloating, rumblings, nausea, etc. It was hell on earth. I don't recommend starting with a normal sized dose.
