I am starting to use actilax fir the first time. I am 76 yrs of age and have used Pru-lax for almost 6months, and it s helped with the my constipation. Actilax has been recommended as a better alternative. I m quite active for my age, like walking everywhere I can, don t smoke or am a heavy drinker. If, I decide to use actax, whouod be the best time to take it, a.m. or p.m ????
