Sodium phosphate enima. Then which type?

My wife was diagnosed with 2.5 mm kidney stone. doctor gave some medicine and ask us to drink fluids along with those. one of the medicine which was pain killer, we stopped it. since it was showing its side-effects like dizziness, dry mouth, nausea and others. problem is while she was on painkiller, she had constipation, from Wednesday to Sunday, she couldn't pass it. On Sunday we tried SODIUM PHOSPHATE Enima. after that, she could pass the stool but, she suffers some side effects, like ankles pain, dry mouth. not only that but she also says she feel dehydrated even though she is drinking a lot of liquid. she feels that her body is warmer than normal. but temprature is Normal. we did ENIMA on Sunday afternoon and i. posting this question on Monday night. she still in that state only. weakness with side-effects. could any one guide us, how long does it take to wear off the side-effects. should i see a doctor, if YES then which type? Thanks in advance.
