"i was on gabapentin when i was younger around age 16 to 18 and i remembered it must had worked pretty well because i stayed on for a little while. so fast forward almost ten years and i started seeing doctor again due to social anxiety and asked if i could try gabapentin. i started low 100mg at night which actually did help me sleep and felt calming effect but i did notice a little twitchy, but all in all it was ok the problem was the next day my anxiety seemed a lot worse i even tried couple more nights and same thing always happened. i&#039;d have physical effect of anxiety, pounding heart, etc. i am also on methadone so i don&#039;t know if this why this medication made me have such bad anxiety next day but everyone is different."
