Insomnia commonly is associated with Bipolar...I almost always have to take my meds to fall asleep and if I'm hypomanic or manic it's much worse. You also have to look at your other symptoms .... Sounds to me like you are hypomanic (I'm not a doc).

You really need a Pdoc to give you a dx and why your health care provider won't just let you see a Pdoc right off the bat is baffling to me. But I guess just play their game, see a Tdoc and hopefully soon after you can see a Pdoc.

As far as the meds, anyone who has Bipolar should be on a mood stabilizer and/or antipsychotics.... yes the weight gain sucks, but it's better then being full blown manic or depressed. I use to only get hypomania or depressed, however my past episode (do to stress and being out of balance) I became truly manic for the first time and it was nooooo fun what so ever, the good feelings of hypomania had left and I was irritable, confused, disoriented, forgetful, etc, etc ... Just awful! So bad I put myself in the hospital.

So, I learned I'm going to have to manage my stress better when I go back to work.... I have no choice, if I don't I will get sick...period.

Good Luck to you
