Mania is when you become a real danger to yourself and others. I know when my old pdoc saw me hypo he would just up my anti-manic med and tell me to try to rest, avoid caffeine, use protection, don't be shy with the PRNs, etc. If he saw me manic he'd say "it's hospital or death at this point" and he'd call my emergency contact to get me to the ER to choice between taking a pill or them ripping my clothes off for a shot. It's also a matter of functioning. Hypo a lot of people have increased functioning compared to baseline. Manic is significantly decreased functioning.
Of course either way you should inform your pdoc and let him figure it out.
