I Take 7.5mg Twice A Day. A.m & P.m. It's

I take 7.5mg twice a day. A.m & p.m. It's been about 9months or alittle more I still am having bad anxiety and wondering what maximum dosage is, that I can take? I am 44 135-140, 5'9. I have trouble sleeping. I have talked to my doctor we were going to increase it. I forgot to ask at appt on Wednesday & now it the weekend. Can I increase it by more. She is aware I wanted o. We spoke about two months ago about it.
