try flaxseed oil or mineral oil. flax seed oil comes in caps and is easy to take. mineral oil is a little gaggy but tasteless. i TBS a day will do it
It sounds alot like Irritable Bowel Syndrome. If you have pain in the abdominal area along with gas, it is quite likely this is your problem. Rather than taking laxatives, it may be wise to try fibre therapy, such as metamucil. If you do have IBS, there is a new medication out for IBS with predominant Constipation called Zelnorm. It is very expensive, but most plans cover it. I hope you get some answers soon.
