I have been taking venlafaxine XL since 1st April. Started on 75mg and was still struggling with sleep. I increased to 112.5mg from 18th April. Since the increase I have been sleeping much better however I am experiencing the most awful tiredness unlike anything I've ever experienced before! This is despite sleeping much better at night. I also feel very shakey a lot of the time. The dr has said he would like to increase me to 150mg from 5th May. Whilst I feel my mood and anxiety have slightly improved I just know I can't cope with this awful tiredness long term. I'm trying my best to keep busy and power through the tiredness every day but it's so hard when your so mentally and physically exhausted. My question is has anybody else experienced these side effects and if so did they get better? If it did get better then how long did that take? I'm very worried about staying on this medication in the hope that the side effects will go and then they don't! I know this is an extremely hard drug to come off and I'm scared that the longer I stay on it and the higher I keep getting my dose increased then the harder it will be to come off! Could really do with some advice. Thank you. Clare
