It's wonderful to hear that you happened upon TSM and had a doc to prescribe. To me, TSM is the sanest method for extricating oneself from that sense of need for a substance that's just supposed to be an occasional bit of fun, or a tasting hobby (for connoisseurs of wine, whiskey, scotch, and even beer).
I'm very much in your camp. No friends--thus no social existence outside the home--and I've got the genes, too: on the paternal side... daddums, brother, an uncle, two cousins; maternal, great gran, great granddad (separate branches, oddly). Am not at all close with my blood relations. Gratefully, I say, I've got my fella of many, many years who has been totally supportive. He wants to drink every day but rarely goes overboard. And... sigh... I'm the one with the nasty streak if I take it too far (violence to self and others, serious Jekyll and Hyde).
I'm really sorry to hear about the arrest. Be kind to yourself.
Regarding the nausea: there are OTC anti-barfiness pills, but I've found a quarter teaspoon of ginger (just the ground, dried spice from the market) in a normal glass of water does the trick--it's healthful for the liver, tum-tum, and cheap!
Hangovers: Regular intake of a B-complex and vitamin C in quantity eliminated the dreadful headaches, vomiting, and some of the energy issues in my case. Not everyone is keen on alternative remedies, so if I sound like a nutter, brush my advice aside. I'm all for what works for YOU.
All the best to you, it sounds as though you're sorting everything out in the swellest of ways.
Ah! Lest I forget, WELCOME!
