BiPolar- Keep an anti-anxiety/anti-depressant strain like an Afghani on hand. Also Kalichakra is a good antidepressant weed.

Pacemaker- Consult with an MD about whether artificially changing heart rate with something other than the pacemaker is even safe!

Arthritis- JillyBean

PMS- Kalichakra or a nice sativa for mood, C99 is outstanding. Some type of Diesel such as East Coast Sour Diesel, Giesel, or NYCD for cramps. I smoked myself into a stupor on Mass Super Skunk (a diesel parent) last time my 'friend' was visiting and was able to skip my monthly 1/4 vicodin, lol... yeah cutting pills in quarters sometimes leads to needing a band-aid, too!
