It's called being an infant and wanting attention from your mommy, being all alone, maybe scared, whatever it is, you need to tend to her needs... some babies can sleep through the night, others wake up 6+ times a night. Just as every individual in life is different, so to are infants.
I am really surprised to see that your answer is to drug up your little baby. This is frightening. Stop with giving her all these toxic drugs, did you ever think that she is having a reaction to all these drugs in her little system ??!!! I wouldn't give her any drugs.
I also wanted to mention that soy formula is so bad for babies. Read a few articles here about it (that could also be the problem):

Infants fed soy formula have an increased risk of:
Food allergies and digestive distress
Behavioral problems
Asthma
Thyroid disorders
Early puberty and fertility problems (including anovulatory cycles; the inability to menstruate)
Cancer -- It's also important for pregnant women to avoid eating non-fermented soy, as a high estrogenic environment in utero may increase their child's subsequent breast cancer risk. Boys could increase their prostate cancer and testicular cancer risk. Vegan moms who use soy as both milk and meat replacements AND are trying to take in more protein are at very high risk.
As you can see, the health risks far outweigh any "benefits" soy formula promises.
Now, we can also add fibroid tumors in adulthood to this list.

Do not let her cry it out - that old theory is barbaric. Turn the tables and think 'how would I feel if the only person in this world who can take care of me abandons me at the very moment I need them most ?' God doesn't do it to us, we shouldn't do it to our kids. Be there when she is crying, comfort her, do you want a trusting bond, where your child knows they can count on you - or do you want to be a mom that is cold, uncaring and your child loses hope...?
Your sleep will come in time, be patient. Every mom knows what you are going through. Try to take naps when your child is sleeping. Just be there for your child - because once they are a few years older, they will be so much more independent and then you will wish for the days when they actually needed you...
