They are checking her therapeutic levels (6-TGN) and her toxicity levels (6-MMP).
It is important while on this medication to check these two (1) because if the medication is not in therapeutic range, the chances of it putting her in and/or keeping her in remission are reduced and (2) if her toxicity levels are over the recommended range, she becomes at-risk for liver damage. If these levels get too high, it will require her to come off of the medication immediately.
These levels may or may not change over time which is why it is important to get routine blood tests for accurate monitoring.
* Low 6-TGN is defined as <235 pmol/8 ×108 and high >450 pmol/8 ×108. High 6-MMP is defined as >5700 pmol/8 ×10

Drinking alcohol in moderation MAY be OK, but your daughter will have to be the one to determine how she feels about this as everyone reacts differently to crohn's and alcohol and alcohol/crohn's/medication combinations.
It is not wise to go overboard with alcohol. These medications when taken are broken down in the liver, putting it to work. Add alcohol to the equation which also makes use of the liver and you are working your liver over-time.
Personally I find the hangovers to be FAR worse since starting 6-mp, a similar medication to Azathioprine. You will hear many people on here say they are fine with a few drinks here and there. You will also hear people say they absolutely cannot tolerate even a few sips of alcohol without feeling like crap while on their maintenance medications.
Aza is not known to have a mental/emotional side effect, I suspect she may be struggling with coming to terms as we all do with this medication. When I first started taking it I spent a few weeks just crying about it because of all of the uncertainty of the disease and the potential risks of medications, but I find that, despite a few minor bumps in the road, it has been helpful to me so far.
I do hope the medication continues to work for her and that she finds a way to cope with this disease. And we are always here on the forum to show support
