Hypomanic Episodes are identical to Manic Episodes with the exception that it is not sufficiently severe enough to cause extreme impairment in social or occupational functions, and is not severe enough to require hospitalization. Caution, some hypomanic episodes can evolve into manic episodes. Alcohol is a drug. Mixing drugs can do a lot of damage. If you would like an occasional drink, talk to your doctor first.
Caffeine is another drug.
It can counteract your medication, and make you feel agitated. There are a lot of alternatives as well as decaffeinated drinks on the market. Again you should check with your doctor. Be aware how much sugar you are taking in. The high may feel good, but don't forget you will come back down.
