I Received Samples To Take From My Doc Yesterday....I Am

I received samples to take from my doc yesterday....I am having digestive issues...rather like flu symptoms but not flu.....had for 2 weeks. Sick to my stomach and/or sometimes pain in lower gut. seems like I want to try and eliminate bowel often.....the feeling and was all over no energy and burpping even on water. Was told to take one capsule after each meal of snack .... wondering, since was given as samples one says Lipase 24,000 and the other larger bottle that has not been opened 38,000.... suggestions?
