Cymbalta and Blood Sugar

[TheTeach]

Okay, I've always had EXCELLENT blood sugar, and I know the data about Cymbalta and A1C (that there can be an increase, but it's typically marginal and generally considered worth the risk).  Anyway, there seems to be a correlation between me starting Cymbalta (initially at 30 mg. coming off Viibryd and gradually getting to my current 90 mg. dosage).  At first the blood sugar spikes weren't very big, but now they are...my blood sugar is high way too often.  My A1C is still within totally normal range, but it's noticeably up.  My pdoc and the NP I see at my primary care doctor both think Cymbalta probably isn't the cause.  There is no other reason I can think of.  I've lost 20 lbs., my diet hasn't changed.  As far as I know there's no infection in my body.  Now this has been going on since December.  The numbers have only really become concerning to me since April.  I used to have blood sugar that often dipped a bit too low, so this is just so weird to me.  I was wondering if anyone else has experienced a significant rise in blood sugar on Cymbalta?  Nothing else changed with my medication, except I went off Buspar (and I doubt that is a factor).  I have tried so many anti-depressants like many of you, and I really like Cymbalta, so I'm really hoping I don't have to go off it, because Viibryd and Trintillex were my other 2 best options, and I had side effects with both of them.  I can't do things like Pristiq because of extreme sweating, which is too bad, because that was the only side effect I had. There are very few anti-depressants I haven't tried. I ended up on Cymbalta (and my pdoc, who I have seen for 15 years was shocked we'd never tried it), because we discovered that Viibryd was a big contributor to my tiredness (I have what is currently diagnosed as Idiopathic Hypersomnia, although my doctors believe it could be Narcolepsy II...it's not Narcolepsy I, because I had a Lumbar Puncture.  I've also had 2 MSLTs, but my doctor says they are irrelevant, because I was on my meds...they did still show Idiopathic Hypersomnia.  After going off all psych meds last Summer (and feeling like I was suffocating most of the time and just feeling like I was living outside my body), I never want to do that again, so I'm content with not knowing which sleep disorder it is since the doctor says it really doesn't make a difference as far as treatment).  It was in slowly going back on my medications that I realized Viibryd was making me tired.  My pdoc and I also then concluded I no longer needed the Buspar.  I haven't missed it at all.  Any experiences with blood sugar and Cymbalta would be helpful!  I appreciate you all!
