Lorazepam was the most disappointing benzo I've ever taken, even at 0.5mg sublingually it didn't feel as therapeutically effective as the equivalent 0.25mg Xanax or 5mg Valium.
This. Lorazepam might as well be placebo pills for me; even in doses as high as 10mg, I did not feel calmer. No buzz, no high, no effect. This is FAR different than when I was prescribed alprazolam; even a 0.25mg pill would calm me down in <10minutes. Hell, just knowing I had something that could calm me down that quickly was calming in itself, and I always had extra pills at the end of the month. Now, high doses of alprazolam (>4mg) is basically asking for trouble
Diazepam is good stuff, but what I gather has active metabolites with LONG half lives. I remember backin 2004 I was prescribed Valium and got busted. I didnt want to detox in jail, so I stopped taking them long before my day in court. They were awful to get off of, took a full six weeks to feel normal again.
Everyone is different, but in my case I was prone (for a while) to major anxiety attacks that were intense. Lorazepam does not help with that, I needed something that worked NOW, and alprazolam works NOW.
If I were to rate the three in terms of withdraw, zero being a cakewalk and 10 being the 7th level of hell, lorazepam (ativan) would be a zero (because it's useless and worthless imo), xanax (alprazolam) would be a 2 (sucks buts it's very short lived), and valium (diazepam) would be a 6. and just for comparison's sake, oxycodone would be a 7, hydromorphone a 9, heroin a 10, and methadone (if done too quickly, which it is in 99% of the cases Ive seen) is about a 13.
Back to the benzos tho, in my experience it's really easy to screw up or overdo it with alprazolam, much moreso than any other benzo Ive tried.
