A few weeks ago I started the slim fast protein shakes. I am wanting to lose weight and have heard that they worked the best for a person on a budget.I would drink one every monring. However, here lately I stopped due to them tasting different then when I first started. I found my self having lose bowel movements as well. I have tried to go back to my cereal and milk that I usually do but am not very sick to my stomach when I yawn and I cannot seem to stop yawning. I have also starting changing the foods I eat to try and lose weight. I guess my concern is should I be going to my doctor or hope that I get over being sick soon? Also do you have any suggestions for weight loss help?
