    1. CONCLUSION: Tolerance to famotidine occurs during continuous administration for 14 days, as previously shown in ranitidine studies.

      This is good for my purposes. It means high doses can be taken for brain effects without disturbing stomach acidity. The question remains, of course, whether coinciding CNS tolerance develops.

    1. We have previously shown that antinociceptive effects of morphine are enhanced in histamine H1 receptor gene knockout mice.

      H1 antihistamines enhance the opioid high in humans. Hospitals sometimes administer antihistamines in combination with opioids. It's not hard to find people online who are using this combination recreationally.

    1. Furthermore, no significant relationship (correlation coefficient: r < 0.3) was observed between beta 1 receptor occupancies of the drugs and the number of dreams. On the other hand, good relationships (r > 0.95) were observed between central and peripheral beta 2 or central 5-HT receptor occupancies and the number of dreams. These findings suggest that beta 2 and/or 5-HT receptor occupancy is superior to beta 1 receptor occupancy as an index for the sleep disorders.

      This suggests that a beta 2 agonist may be appropriate for sleep.

      Note: they appear to be talking about the number of dreams recalled (due to awakenings) rather than the actual number of dreams.

    1. Analysis of the subjective questionnaires showed that recollection of dreaming and awakening in the night was increased by the three lipophilic drugs, propranolol, metoprolol, and pindolol. These results confirm reports in the literature but are contrary to those expected from considering the effects of noradrenaline on sleep. Analysis of physiological records confirmed subjects' reports that waking was increased by the lipophilic drugs. Dreaming (rapid eye movement sleep, REM) was reduced, as predicted from knowledge of the effect of noradrenaline on sleep. Increased awakening leads to an increase in remembered dreaming which explains the otherwise paradoxical results.

      Surprisingly, beta-blockers, unlike alpha-blockers, appear to impair sleep.

    2. These results confirm reports in the literature but are contrary to those expected from considering the effects of noradrenaline on sleep.

Increased awakening leads to an increase in remembered dreaming which explains the otherwise paradoxical results.

      Surprisingly, beta-blockers, unlike alpha-blockers, appear detrimental to sleep. I would speculate that this could be the result of a shift in autonomic tone, similar to how caffeine tends to lower heart rate.
