I prefer xanax. It comes in a .25 mg which is a pretty small amount and it can be taken only as needed. I don't notice any C from it but its a chance. Its out of your system really quickly so no worries about using before you get pg. Once you start trying I wouldn't use it but its would be just fine for the occasional use between now and than.
I used to take the .5mg 4 or 5 times a day right after losing the twins but now, I just take it at bedtime and once in a while during the day if I am having a particulary bad day. It just has a calming affect and helps you relax. It can make some people tired the first few times you take it. Its also really cheap!
