Honestly, I really think you should start the acacia. I eat even less than you but it still helps. I don't get any cramps from it and at most I have mild gas but I think id have that anyways. No bloating either. I think thats why the acacia is unique because it doesn't cause all the side affects that other fiber supplements do. It hasn't made my BM improve TOO much but it has definately helped with the cramps which is really my worst symptom. I know you may have to wait months though to get relief from constipation but I am willing to wait and keep taking it because it really doesn't cause me any trouble so why not? Alwaaaays keep in mind though, that it will more than likely take a while to see some results but it is definately worth waiting especially if it doesn't make you feel any worse, ya know? Try a 1/2 teaspoon at night and see how you feel in the morning and then take another 1/2 tsp. Hopefully you might see a little relief. The first morning after I took it I had a pretty normal BM!! That was only one time and I think it may have just been a shock of fiber hahaha but it was more than welcomed!
