Those sort of side effects typically resolve as your body acclimates. If it is just too much to deal with, contact Dr. Shen to see about a lower dose. It is the Elavil (tricyclic antidepressant) that is supposed to help with IPS. A lower dose than what is needed to treat depression is prescribed. Some people are more sensitive to the side effects and need to start with a very low dose. This drug is for regular use.
The Ativan is for the anxiety, and for just occasional use, so not as helpful for controlling IPS. It can make you drowsy too.
